Detailed Description

template<std::size_t ThePrecision, std::size_t TheScale>
struct Lightweight::SqlNumeric< ThePrecision, TheScale >

Represents a fixed-point number with a given precision and scale.

Precision is exactly the total number of digits in the number, including the digits after the decimal point.

Scale is the number of digits after the decimal point.
