Title:  Useful Math Tool for Casio Calculator 
Author: (Pelle Otterholm <pelleo@update.uu.se>)


Here I hand over a useful tool for the Casio calculator
It is a program that  calculates the result of < A modulo B >.
You who know about this mathematical phenomenon know how useful this
tool could be.
The two upper versions is programmed for the casio belonging to the
9950-type. The other two versions is possible to use on any casio
calculator. The programs is designed to be called by other programs and
return the result in a variable.

NOTE :for models belonging to the 9950-type.
I have detected that the versions for 9950-type is slower than the other
versions ( I tried this by recursively call the program n times and
timed this. I compared the version II-types). So I recommend you to use
the version for  "other models" if you want the quickest calculation (if
you just use one calculation, you would not detect any difference).
 

Version I : Minimum use of variables ( that results that the first
variable input will be erased by the result of the calculation )

Program A MOD B

 BFrac (A/B ->A
 If A<0
 Then A+B
 IfEnd

Version II : use of variables that does not affect the input variables
when calculation is done

 BFrac (A/B ->C
 If C<0
 Then C+B
 IfEnd

For other models :

Version I : Minimum use of variables ( that results that the first
variable input will be erased by the result of the calculation )

 BFrac (A/B ->A
 A<0 => A+B

Version II : use of variables that does not affect the input variables
when calculation is done

 BFrac (A/B ->C
 C<0=>C+B


Comments :
 Verion I programs :
   Variables used : A,B
   Input variables : A,B
   Returning variables : A

 Version II programs
   Variables used : A,B,C
   Input variables : A,B
   Returning variables : C
