Converting Int to Float or Float to Int using Bitwise operations (software floating point)

Question

I was wondering if you could help explain the process on converting an integer to float, or a float to an integer. For my class, we are to do this using only bitwise operato

Answer 1

Have you checked the IEEE 754 floating-point representation?

In 32-bit normalized form, it has (mantissa's) sign bit, 8-bit exponent (excess-127, I think) and 23-bit mantissa in "decimal" except that the "0." is dropped (always in that form) and the radix is 2, not 10. That is: the MSB value is 1/2, the next bit 1/4 and so on.
