Why does Decimal created from a float still show unexpected digits?
KitForma editorial guide. Converting a float to Decimal preserves the float’s binary approximation. It cannot reconstruct the decimal text that existed before that approximation.
Step-by-step answer
Converting a float to Decimal preserves the float’s binary approximation. It cannot reconstruct the decimal text that existed before that approximation.
For a decimal contract, construct from input text:
Decimal("0.1"), then apply an explicit precision and rounding rule at the required business boundary. Compare this with Decimal(0.1) in a small test. Keep intermediate calculations at sufficient precision and quantize only where the specification calls for it. Decimal is not a substitute for choosing units, rounding policy or tax rules. If the original value has already been rounded upstream, receiving it as Decimal does not restore lost information.Sources and verification
