Detailed Description

template<typename T, int MinDigits, int MaxDigits, typename = void>
struct DigitCounter< T, MinDigits, MaxDigits, typename >

Functor that calculates the number of digits in an unsigned integer using binary search.

The code for doing the binary search is generated and unrolled at compile time.

Template Parameters

T	the unsigned integer type of the input to the functor
MinDigits	the minimum number of digits the integer is known to have
MaxDigits	the maximum number of digits the integer is known to have
