[issue44910] Floating point issue

Eric,

I was unaware of this document and its implementation in python.

where
0.01+0.15 = 0.16 but 0.01+273.15=273.15999999999997

the latter which should be 273.16 which is triple point temperature of water in Kelvin.

This floating point variance explains some if the conditional test failures I have encountered.

regards

Alan

This a limitation of the floating point type that python uses. See https://docs.python.org/3/tutorial/floatingpoint.html
