- The <xref:System.Decimal.op_Modulus%2A> method defines the operation of the modulus operator for <xref:System.Decimal> values. It enables code such as the following:

- If the language you're using doesn't support custom operators, call the <xref:System.Decimal.Remainder%2A> method instead. 
+ The sign of the value returned by the remainder operation depends on the sign of dividend. If dividend is positive, the remainder operation returns a positive result; if it is negative, the remainder operation returns a negative result.
