Introduction We know that Microsoft.. NET Framework. the decimal structure (in the C # language, the medium price is the decimal keyword) is used to represent the decimal number, ranging from-(296-1) to 296-1, and can have 28 decimal places. This means: Decimal. min

The position of the decimal point is fixed. We are going to use integers to represent fixed-point decimals, because the decimal point position is fixed, so there is no need to store it (if the location of the decimal point is stored, that is floating point). Since there is no place to store the decimal point, the compu

It's always strange why a decimal is added to the pre-defined data type of C #. Isn't float and double enough? I am going to dig it out today.

It's been weird. Why is a decimal added to the predefined data types of C #, and is it enough to have float and double? Come and dig a hole today.
