How It Works
Total minutes = decimal hours × 60, since there are exactly 60 minutes in one hour. To produce the hours-and-minutes breakdown, the whole-number portion of the decimal is taken as the hour count using Math.floor(). The fractional part — decimal hours minus the whole hours — is multiplied by 60 and rounded to the nearest whole minute. For example, 2.75 hours: total minutes = 2.75 × 60 = 165; whole hours = 2; fractional part = 0.75; remaining minutes = 0.75 × 60 = 45. So the result is 165 total minutes, or 2 hours and 45 minutes. Rounding is applied to the minutes display only; the raw total minutes retains two decimal places for precision.
