I have two float values, 'a' and 'b'.
I need to calculate the reminder of these two float values, and it must be a float value.
Let
float a = 1.1;
float b = 0.5;
So the remainder 'r' should be accurate value
ie r = a % b
r = 1.1 % 0.5
0.5) 1.1 (2
1.0
______
0.1
r = 0.1
But it causes to an error invalid operand for float values.
How to do it?
In C, C++ and Objective-C that would be fmod
.
use fmod()
#include <math.h>
double x,y,z;
x = 1.1;
y = 0.5;
z = fmod(x,y)
Don't tforget the -lm liker flag if you are on linux/unix/mac-osx/.
for more info
$man fmod
Try out
float x = (float)(1.1 % 0.5);
NSLog(@"%f",x);
Hope this helps.
did you declare it?
float r;
you have to do that before you could do any calculations
so
float r;
float a = 1.1;
float b = 0.5;
r = a % b;
