 HP 48GX: Progam for adding feet and inches?Message #1 Posted by Dan on 18 Jan 2001, 3:54 p.m. I posted the 48GX question for adding fractions. Actually, I need a program that will add feet and inches in 32nds of an inch. EX: 4'3 15/32" + 2'4 16/32" = 6'7 31/32" There are construction calculators that you enter this in as follows: 4 3 15 + 2 4 16 = 6 7 31 There has to be a program because HP's can do anything. Thanks.

 Re: HP 48GX: Progam for adding feet and inches?Message #3 Posted by Mike on 18 Jan 2001, 6:56 p.m.,in response to message #1 by Dan I am asking because I was thinking how I would program it. How does it add 4'3 13/16" + 2'4 7/16" = 6'8 4/16" = 6'8 1/4" 4 3 13 + 2 4 7 = 6 8 4 Does it assume that the fractions entered are always 32nd's or does it have a mode? I realize you said this "Actually, I need a program that will add feet and inches in 32nds of an inch" but saying 8/32 instead of a quarter inch seems odd. Is it always true that you mean 32nds? Do you need - * / ...... ?

The construction calculator in our office uses a set denomenator (16ths). So when you have 1/4", you enter 4 in as the last number. It must be easier to program that way. If you come up with a program, I'd appreciate it if you'd let me take a look at it. I'm not that fluent in programming a 48GX, but I'll get there. Without the set denomenator would be perfect. Thanks.
