What does the C++ standard state the size of int, long type to be?

Question

I\'m looking for detailed information regarding the size of basic C++ types. I know that it depends on the architecture (16 bits, 32 bits, 64 bits) and the compiler.

Answer 1

For floating point numbers there is a standard (IEEE754): floats are 32 bit and doubles are 64. This is a hardware standard, not a C++ standard, so compilers could theoretically define float and double to some other size, but in practice I've never seen an architecture that used anything different.
