* [PATCH v1] Fix floating-point noise in pg_stat_us_to_ms()
@ 2026-06-29 06:31 Bertrand Drouvot <[email protected]>

From: Bertrand Drouvot @ 2026-06-29 06:31 UTC (permalink / raw)

Multiplying by 0.001 can produce trailing-digit noise in displayed
values (for example 0.009000000000000001 instead of 0.009, should extra_float_digits
not being set to 0) because 0.001 cannot be represented exactly in binary floating
point.

Use division by 1000.0 instead as it is the most common way to deal with such
computation in the code tree.

* [PATCH v1] Fix floating-point noise in pg_stat_us_to_ms()
@ 2026-06-29 06:31 Bertrand Drouvot <[email protected]>

From: Bertrand Drouvot @ 2026-06-29 06:31 UTC (permalink / raw)

Multiplying by 0.001 can produce trailing-digit noise in displayed
values (for example 0.009000000000000001 instead of 0.009, should extra_float_digits
not being set to 0) because 0.001 cannot be represented exactly in binary floating
point.

Use division by 1000.0 instead as it is the most common way to deal with such
computation in the code tree.

values (for example 0.009000000000000001 instead of 0.009, should extra_float_digits
not being set to 0) because 0.001 cannot be represented exactly in binary floating
point.

Use division by 1000.0 instead as it is the most common way to deal with such
computation in the code tree.

* [PATCH v1] Fix floating-point noise in pg_stat_us_to_ms()
@ 2026-06-29 06:31 Bertrand Drouvot <[email protected]>

From: Bertrand Drouvot @ 2026-06-29 06:31 UTC (permalink / raw)

Multiplying by 0.001 can produce trailing-digit noise in displayed
values (for example 0.009000000000000001 instead of 0.009, should extra_float_digits
not being set to 0) because 0.001 cannot be represented exactly in binary floating
point.

Use division by 1000.0 instead as it is the most common way to deal with such
computation in the code tree.

* [PATCH v1] Fix floating-point noise in pg_stat_us_to_ms()
@ 2026-06-29 06:31 Bertrand Drouvot <[email protected]>

From: Bertrand Drouvot @ 2026-06-29 06:31 UTC (permalink / raw)

Multiplying by 0.001 can produce trailing-digit noise in displayed
values (for example 0.009000000000000001 instead of 0.009, should extra_float_digits
not being set to 0) because 0.001 cannot be represented exactly in binary floating
point.

Use division by 1000.0 instead as it is the most common way to deal with such
computation in the code tree.

values (for example 0.009000000000000001 instead of 0.009, should extra_float_digits
not being set to 0) because 0.001 cannot be represented exactly in binary floating
point.

Use division by 1000.0 instead as it is the most common way to deal with such
computation in the code tree.

* [PATCH v1] Fix floating-point noise in pg_stat_us_to_ms()
@ 2026-06-29 06:31 Bertrand Drouvot <[email protected]>

From: Bertrand Drouvot @ 2026-06-29 06:31 UTC (permalink / raw)

Multiplying by 0.001 can produce trailing-digit noise in displayed
values (for example 0.009000000000000001 instead of 0.009, should extra_float_digits
not being set to 0) because 0.001 cannot be represented exactly in binary floating
point.

Use division by 1000.0 instead as it is the most common way to deal with such
computation in the code tree.

* [PATCH v1] Fix floating-point noise in pg_stat_us_to_ms()
@ 2026-06-29 06:31 Bertrand Drouvot <[email protected]>

From: Bertrand Drouvot @ 2026-06-29 06:31 UTC (permalink / raw)

Multiplying by 0.001 can produce trailing-digit noise in displayed
values (for example 0.009000000000000001 instead of 0.009, should extra_float_digits
not being set to 0) because 0.001 cannot be represented exactly in binary floating
point.

Use division by 1000.0 instead as it is the most common way to deal with such
computation in the code tree.

values (for example 0.009000000000000001 instead of 0.009, should extra_float_digits
not being set to 0) because 0.001 cannot be represented exactly in binary floating
point.

Use division by 1000.0 instead as it is the most common way to deal with such
computation in the code tree.

* [PATCH v1] Fix floating-point noise in pg_stat_us_to_ms()
@ 2026-06-29 06:31 Bertrand Drouvot <[email protected]>

From: Bertrand Drouvot @ 2026-06-29 06:31 UTC (permalink / raw)

Multiplying by 0.001 can produce trailing-digit noise in displayed
values (for example 0.009000000000000001 instead of 0.009, should extra_float_digits
not being set to 0) because 0.001 cannot be represented exactly in binary floating
point.

Use division by 1000.0 instead as it is the most common way to deal with such
computation in the code tree.

* [PATCH v1] Fix floating-point noise in pg_stat_us_to_ms()
@ 2026-06-29 06:31 Bertrand Drouvot <[email protected]>

From: Bertrand Drouvot @ 2026-06-29 06:31 UTC (permalink / raw)

Multiplying by 0.001 can produce trailing-digit noise in displayed
values (for example 0.009000000000000001 instead of 0.009, should extra_float_digits
not being set to 0) because 0.001 cannot be represented exactly in binary floating
point.

Use division by 1000.0 instead as it is the most common way to deal with such
computation in the code tree.

values (for example 0.009000000000000001 instead of 0.009, should extra_float_digits
not being set to 0) because 0.001 cannot be represented exactly in binary floating
point.

Use division by 1000.0 instead as it is the most common way to deal with such
computation in the code tree.

* [PATCH v1] Fix floating-point noise in pg_stat_us_to_ms()
@ 2026-06-29 06:31 Bertrand Drouvot <[email protected]>

From: Bertrand Drouvot @ 2026-06-29 06:31 UTC (permalink / raw)

Multiplying by 0.001 can produce trailing-digit noise in displayed
values (for example 0.009000000000000001 instead of 0.009, should extra_float_digits
not being set to 0) because 0.001 cannot be represented exactly in binary floating
point.

Use division by 1000.0 instead as it is the most common way to deal with such
computation in the code tree.

* [PATCH v1] Fix floating-point noise in pg_stat_us_to_ms()
@ 2026-06-29 06:31 Bertrand Drouvot <[email protected]>

From: Bertrand Drouvot @ 2026-06-29 06:31 UTC (permalink / raw)

Multiplying by 0.001 can produce trailing-digit noise in displayed
values (for example 0.009000000000000001 instead of 0.009, should extra_float_digits
not being set to 0) because 0.001 cannot be represented exactly in binary floating
point.

Use division by 1000.0 instead as it is the most common way to deal with such
computation in the code tree.

values (for example 0.009000000000000001 instead of 0.009, should extra_float_digits
not being set to 0) because 0.001 cannot be represented exactly in binary floating
point.

Use division by 1000.0 instead as it is the most common way to deal with such
computation in the code tree.

* [PATCH v1] Fix floating-point noise in pg_stat_us_to_ms()
@ 2026-06-29 06:31 Bertrand Drouvot <[email protected]>

From: Bertrand Drouvot @ 2026-06-29 06:31 UTC (permalink / raw)

Multiplying by 0.001 can produce trailing-digit noise in displayed
values (for example 0.009000000000000001 instead of 0.009, should extra_float_digits
not being set to 0) because 0.001 cannot be represented exactly in binary floating
point.

Use division by 1000.0 instead as it is the most common way to deal with such
computation in the code tree.

* [PATCH v1] Fix floating-point noise in pg_stat_us_to_ms()

Multiplying by 0.001 can produce trailing-digit noise in displayed
values (for example 0.009000000000000001 instead of 0.009, should extra_float_digits
not being set to 0) because 0.001 cannot be represented exactly in binary floating
point.

Use division by 1000.0 instead as it is the most common way to deal with such
computation in the code tree.

Hi hackers,

while reviewing [1], I noticed that the IO timings displayed in pg_stat_io can 
produce floating-point noise like:

postgres=# select read_time from pg_stat_io where read_time > 0;
      read_time
---------------------
  2.2640000000000002
 0.08700000000000001

That's because 0.001 cannot be represented exactly in binary floating
point. I think this output looks weird, even if understandable. Note that with
extra_float_digits set to 0 you don't see the noise (but 1 is the default).

The attached patch changes pg_stat_us_to_ms() so that it uses a division
by 1000.0 instead as it's correctly rounded, see for example:

postgres=# SELECT (9 * 0.001::float8)::text;
         text
----------------------
 0.009000000000000001
(1 row)

postgres=# SELECT (9::float8 / 1000.0)::text;
 text
-------
 0.009
(1 row)

Given that / 1000.0 is the most common way to do this kind of computation in the
code tree, I think that it makes sense to update pg_stat_us_to_ms() to do so.

Thoughts?

Yes, multiplying by that constant also multiplies the rounding error.

+1, I'll take care of this.
