float reinterpret_int(u32 A) { float B; memcpy(&B, &A, 4); return(B); } Both pointer recast and union appear to be shunned by C purists. Some compilers detect the operations as errors. The memcpy method moves it out of the compiler's view. The dirty deed in done out of sight ...

Toconvertfrom onetypeto another inCand otherprogramming languages. Tocastto a newtype, use the new type surrounded inbrackets before the old value. egint foo = (int)3.33333; //foo = 3 InC++, casts can beoverloaded, for instance to make a class return a rounded up float member when cast...
