Not performing multiplication and division operation with decimal number in PIC

[ecaits]

Dear All,

I cannot perform multiplication and division with integer number in pic 16f877 using hi-tech c compiler.


What is reason behind that???

I cannot perform below code.

#include<pic.h>
#include<htc.h>
#include<stdlib.h>
#include<math.h>

void main()
{

	unsigned int i=12,t=0,k=0,b=0;
	float j=0;

	t=i;
	b=i*0x2;
	k=i/0x3;
	j=i;

}

for multiplication i/0*3 not i/0x3

you have to write in a language that complier understands ! :wink:

If i make same thing which you suggested then also the given code not performing maths operation....

put while(1) loop in your main routine .

0x3 is the hexadecimal form of decimal 3 or binary 0b11 , why do you think that the compiler doesn't understand it?

i/0*3

Division by 0 is not a good idea

You didn't tell a word about the observed problem.

I expect this results t=12 b=24 k=4 j=12.000

what does it show ? error, or show nothing, or showing other than what you are expecting ?

alexan_e,

You are right , sorry, i over went the concept !

Yes sir, you are right, now i m getting same value.

But Now, I want to divide j say j/5, then i m not getting expected value???

 

[nick703]

j is float right and this result is store in which variable u do not described?
