HMS-
Synopsis
Subtracts times in hours / minutes / seconds format
Description
The HMS-
command subtracts two values representing hours / minutes / seconds returning a value in the same format. The input is expressed by a real number in the format HH.MMSS, where:
- HH are the hours;
- MM are the minutes;
- SS are the seconds.
It is not mandatory that MM or SS are less than 60. In fact, they can be up to 99: in any case HMS-
will compute the correct result. An useful consequence derives from this property: if Rtime-hms2 is 0 HMS-
can be used to normalize a time value so that both MM and SS are less than 60.
Compatibility
HMS-
is not fully equivalent to its userRPL counterpart.
In particular:
- in userRPL the time value can express fractions of seconds too; in newRPL it is not allowed.
