Chapter 2, Problem 2.96HW

Following the bit-level floating-point coding rules, implement the function with the following prototype:

/*

* Compute 1(int) If.

* If conversion causes overflow or f is NaN, return 0x80000000

*/

int float_f21(float_bits f);

  For floating-point number f, this function computes (int) f. Your function should round toward zero. If f cannot be represented as an integer (e.g., it is out of range, or it is NaN), then the function should return 0x80000000.

  Test your function by evaluating it for all 2³² values of argument f and comparing the result to what would be obtained using your machine’s floating-point operations.
