static const int max_exponent10;
(until C++11)static constexpr int max_exponent10;
(since C++11)The value of std::numeric_limits<T>::max_exponent10 is the largest positive number n such that \(\scriptsize 10^n\)10n
is a representable finite value of the floating-point type T.

Demonstrates the relationships of max_exponent, max_exponent10, and max() for the type float:
Output:
max() = 3.40282e+38 max_exponent10 = 38 max() = 0x1.fffffep+127 max_exponent = 128[edit] See also one more than the largest integer power of the radix that is a valid finite floating-point value
