Ask HN: Naming convention for a percentage stored as a value from 0 to 1
Say you’re storing a percentage like “state tax”. You store it as a decimal: 0.4 means 40%. What do you call this type when you need to name a db column or a variable? Technically it is not a percent until you * 100.
“Decimal fraction” seems most correct but is very verbose. No one is writing taxRateDecimalFraction as a var name.
- PaulHoule 3y agoJust "fraction".
- warrenm 3y agohow about `taxrate`? Or don't store it as a decimal between 0 and 1 - but as a value between 0 and 100 (with possible decimal points, of course), and just call it `taxpct`?
- warrenm 3y ago>No one is writing taxRateDecimalFraction as a var name. Wait til you see Java or Hungarian Notation
- bell-cot 3y ago"rate", or "tax_rate", or "state_rate", or "state_tax_rate".
