RE: H->HMS conversion HP-15C vs. HP42S vs HP67
Hello,

Please note the proposed patch in my DEG->DMS formula to fix the "60 seconds" bug by naturally rounding to internal precision:

INT(X*60) is transformed into INT(X*120/2)
INT(X) is transformed into INT(X*2/2)

(patched): DEG->DMS: (90*X+INT(X*120/2)+100*INT(X*2/2))/250
(unchanged): DMS->DEG: (250*X-INT(100*X)-60*INT(X))/90

What do you think of it ?
