My life got infinitely easier once I learnt the financial world all use integers in cents to do their money calculations.
- quicklime 4y agoNot all, many situations make use of prices and calculations in the fractions of a cent. For example forex trading, or even gas stations.
- pixiemaster 4y agostill those probably are treated as Integer of a millionth cent
- singingfish 4y agoGenerally decicents (10 decicents = 1 cent) makes all normal currency calculations much easier/reliable. If you need lower resolution use millicents or microcents
- pedrovhb 4y agoIs that the case? I was under the impression that Decimals were used in financial contexts because (besides preventing floating point error) you can define how to handle things such as rounding behavior. For instance, at least in Python, 3//2 == 1 while -3//2 == -2; integer division is rounded down, and not towards zero as one may expect. Decimal lets you pick how you want that to go.
