(12C) Fractional Part Function

[Gamo]

The HP-55 doesn't have FRAC and INT funtions and I'm happen to see some
program example from HP-55 User's Manual that program the fractional
part routine in program.

Try this Fractional Part routine and it work as expected on HP-12C
Since this type of problem still exist on some programmble calculator that doesn't have
these funtion, couple friend of my have ask me about this type of problem before and I
didn' t know any good solution yet, until now.

This FRAC functions routine only work on "Positive Integer"

Example: FIX 9

2 [√X] display 1.414213562

[R/S] display 0.414213562
--------------------------------
355 [ENTER] 113 [÷] display 3.141592920

[R/S] display 0.141592920

Program: FRAC function

Quote:01 ENTER
02 ENTER
03 EEX
04 9
05 +
06 LSTx
07 -
08 1
09 -
10 -
11 1
12 X≤Y
13 GTO 16
14 Rv // Roll Down
15 GTO 00
16 -

Remark: Program line 03 to 07 by itself canbe use as INT function.
