Description

The HMS+ command adds 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 either R_time-hms1 or R_time-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.
