Question

32 bits are represented in binary using the IEEE format. So how can I extract those bits?
Bitwise operations like & and | do not work on them!
what i basically want to do is extract the LSB from 32 bit float images in opencv
thanx in advance!

Answer 1

#include<stdio.h>
union abc
{
    float fo;
    unsigned int no;
};
int main()
{   
    union abc test;
    test.fo=36.5;
    unsigned int x=test.no;
    for( int i = 0; i < sizeof(float)*8; i++ )
    {
        printf("%d", x & 0x1);
        x = x >> 1;
    }

    return 0;
}

this was a way to extract the bits of the float!
