> The implementation of float is not explicitly defined in the c99 specification

I do not like to be a smartass, but it is defined very explicitly in the C language standard - floating point types match the types defined in IEC 60559, which is equivalent to IEEE 754.

Only if __STDC_IEC_559__ is defined, which implementations are not required to do (in C++, the equivalent is std::numeric_limits<float>::is_iec559).

Hehe, serves me right! ;-)

Thanks for the correction!

Does not have much to do with OpenBSD per se.

Makes sense, kinda. But here is an example:

> The implementation for float uses four bytes, which yields a complexity of log_2(2^{8∗4} ∗ 2^4).

Looks like this complexity metric combines the "internal" complexity of an object (the number of bits) with the "external" complexity (the number of bytes). Sure, although I do not think that the logarithm plays any useful role here.
