How to calculate hour:minutes from total minutes?

问题

For example i have 525 minutes, if we will divide it by 60 the result will be 8.75

But 1 hour have only 60 minutes not 75

How can i calculate the exact hour:minutes from total minutes?

回答1:

$hours = intval($totalMinutes/60);
$minutes = $totalMinutes - ($hours * 60);

Edited to be PHP

This kind of conversion is done using integer division and the modulo operator. With integer division you find out how many of the "large" unit you have and with modulo you find out how many of the "small" unit are left over:

define('MINUTES_PER_HOUR', 60);

$total_minutes = 525;
$hours = intval($total_minutes / MINUTES_PER_HOUR);  // integer division
$mins = $total_minutes % MINUTES_PER_HOUR;           // modulo

printf("%d minutes is really %02d:%02d.\n", $total_minutes, $hours, $mins);

See it in action.

floor(525 / 60) gives the number of hours (8.75 rounded down to 8).

525 % 60 gives the number of minutes (modulo operator).

What I did for my girl friend made her chart with 60 min intervals eg 1=60,2=120,3=180,4=240,5=300,6=360 etc etc. then I told her to get her minutes eg 337 find the closest number without going over that would be 5 then use the number 5 equals and subtract it from your original minutes 337-300=37 the remainder is the minutes thus 337 minutes equals 5 hours and 37 minutes
