Calculate your daily water consumption

  movaps xmm1, TimeSF(Input$("older date: ", fDate$(-30)))     ; suggest thirty days before today

  Inkey Str$("Consumption per day: %3f units", ST(0)v)         ; calculate consumption per day
EndOfCode


The strings "500", fDate$(-30) and fDate$() are suggestions and can be edited by the user with the arrow and backspace keys. The consumption can be any number, e.g. 1.5; the dates must be entered in the correct format dd.mm.yyyy - sorry, U.S. format won't work :cool:

Example:

Code: [Select]
Consumption: 500
older date: 29.01.2022
newer date: 29.05.2022
120 days between the two dates
Consumption per day: 4.17 units
