c - Manually doing soft-float add -

-

i need write program in c takes 2 floating point numbers , produces sum output using int, pointers , malloc(). no other data type. (single precision) , i'm helpless.

good read: what every programmer should know floating-point arithmetic

edit: understood question exercise understand floating point numbers. maybe i'm wrong…
