| float type pointers |

Hello,
I can not seem to get the correct results when working with float type variable. I have an example of what i am trying to do below. first passing a some float parameters and observing the result, doing the same operation without passing. Is there something that i am missing??
| Code: |
#include <16F877>
#device *=16
#fuses HS,NOWDT,NOPROTECT,NOLVP,NOBROWNOUT,NOPUT,NOPROTECT,NOWRT,NOCPD
#use delay(clock=20000000)
void point_back_float(float *a, float *b, float *c){
*c = a/b;
}
void main(){
float a=3.0,b=10.0,c = 0;
point_back_float(&a,&b,&c); //pass operation
c = a/b; //internal operation
}

If you pass everything with a pointer, then you have to de-reference
everything. Example of how to fix it:
