I came across some minor issues in some math man pages. M. logb: The formula "floor(log2(x))" should be "floor(log2(fabs(x)))". (Or ...abs(...) if it's meant to be math and not C.) significand: The range [1,2) should be [1,FLT_RADIX) cbrt: The phrase "every representable real value has a representable real cube root" is wrong. In fact, a representable cube root is quite rare. This should be something like "every representable real value has a real cube root and rounding it to a representable value never causes overflow or underflow." log2, log10: These use, e.g., "base 2 logarithm". Compare that to exp2's "base-2 exponential" (with a hyphen). I am leaning towards the hyphenated version being correct, but I am not a native English speaker. exp10: The man page probably should come with a warning not to use the function for the time being. The implementation is pretty bad. For example, results for integer arguments 3, 4, 7, 8, 9, and 17 are needlessly inaccurate. pow(10,x) is much better, but not perfect.
