Python – comparing floats and decimals
No matter how old I get, I keep being bitten by the joys of having some data as floats and some as decimals. [cc lang=”python”] ipdb> value Decimal(‘1.473’) ipdb> from_value 1.473 ipdb> value < from_value True [/cc] because ... [cc lang="python"] ipdb> from decimal import * ipdb> Decimal(from_value) Decimal(‘1.4730000000000000870414851306122727692127227783203125’) [/cc] So work out what accuracy you need and do something like [cc lang=”python”] from_value = Decimal(from_value).quantize(Decimal(‘0.0001’)) [/cc]
