Decimal

Synopsis

This simple value type is commonly used for financial calculations, which can preserve a significant number of fractional digits with no round-off error. Decimals are stored as 12-byte signed integers scaled by a variable power of 10. This means that a decimal data type can effectively hold 28 significant digits without losing any information. With a scale of 0 (no decimal places), the largest possible value is approximately 7.92x10²⁸. This type is available in C# through the decimal alias.
