How do you access individual bits of a floating point number in the C programming language?

#include <stdio.h> 
 
int main(){ 
        printf("%d, %d\n", sizeof(float), sizeof(long)); 
        // to show they are both 4 bytes 
        union uni{float f; long i;} u; 
        u.f = 123.456; 
        printf("%lX\n", u.i); // show bits in hex 
        int i; 
        for(i = 0; i<32; i++){ 
                // all bits, reversed: 
                putchar('0' + (u.i & 1)); 
                u.i >>= 1; 
        }         
}
