Convert decimal representing time to hour, minutes, seconds

Question

I have a decimal. The range of this decimal is between 0 and 23.999999. This decimal represents a time. For example, if the decimal is 0.25, then the time it represents is 1

Answer 1

Whatever language you use, you can do this using the math functions: MOD and FLOOR/TRUNC

Let "dec" be the decimal variable

trunc(mod(dec, 1)) => hours
trunc(mod(dec * 60, 60)) => minutes
trunc(mod(dec * 3600, 60)) => seconds

In C#, you can truncate a decimal to int using just explicit casting, e.g.

int seconds = (int) ((dec * 3600) % 60)
