Function definition for “float_le()” function:

The implementation for “float_le()” and “f2u()”function is given below:

//Header file

#include <stdio.h>

#include <assert.h>

//Function definition for returns the result as an unsigned

unsigned f2u(float xvl)

{

/* Returns the unsigned value by using "(unsigned)&x" /

return (unsigned)&xvl;

}

//Function definition for float_le function

int float_le(float x, float y)

{

//Compute the unsigned value for "x"

unsigned ux = f2u(x);

//Compute the unsigned value for "y"

unsigned uy = f2u(y);

//Get the sign bits for "x"

unsigned sx = ux >> 31;

//Get the sign bits for "y"

unsigned sy = uy >> 31;

/ Returns the result for float_le() function /

return (ux << 1 == 0 && uy << 1 == 0) ||

    (sx && !sy) ||

    (!sx && !sy && ux <= uy) ||

    (sx && sy && ux >= uy);

}

//Main function

int main(int argc, char argv[])

{

/* Call function "float_le" with checking value using "assert" function */

assert(float_le(-0, +0));

assert(float_le(+0, -0));

assert(float_le(0, 6));

assert(float_le(-8, 8));

return 0;

}

The given code is used to check whether its first argument in given function is less than or equal to its second argument...
