Detailed Description

The collection of useful utilities for evaluation of decimal digits for the unsigned integral values.

The utilities for evaluation of Nth decimal digit for the unsigned integral values:

Gaudi::Math::IDigit The most efficient compile-time evaluator. It is applicable if both N and value are compile-time constanst
Gaudi::Math::Digit Rather efficient fuctor, N is compile-time constanst
Gaudi::Math::digit The regular function, the least efficient evaluator

The utilities for evaluation of decimal N1->N2 decimal digits for the unsigned integral values:

Gaudi::Math::IDigits The most efficient compile-time evaluator. It is applicable if both N1/N2 and value are compile-time constanst
Gaudi::Math::Digits Rather efficient fuctor, N1&N2 are compile-time constanst
Gaudi::Math::digits The regular function, the least efficient evaluator
