int mul test
Essentially this is a while loop which takes two integers (x=54;y=82;) and multiplies them (z=x*y).

int div test
Essentially this is a while loop which takes two integers (x=54;y=82;) and multiplies them (z=y/x).

fp add test
This is a while loop which takes two doubles and adds them just like in the int add test.

A while loop which takes two doubles and subtracts them.

fp mul test
A while loop which takes two doubles and multiplies them. Within the loop, we take two doubles, so we are multiplying the same numbers again and again. This should avoid overflow.

A while loop which takes two doubles and divides them.
