* fix binary transfer floating point overflow

https://github.com/pgjdbc/pgjdbc/issues/2696


for float4 and float8 only use BigDecimal for values outside range of
java int.

float4 convert to double for BigDecimal calculation
this maintains the precision present in the binary value even if the
string representation strips it

* binary floating point math :(
