Why use Decimal.Multiply vs operator multiply?

Question

decimal result = 100 * 200; 

vs

decimal result = Decimal.Multiply(100, 200); 

Answer 1

Using the Decimal.Multiply will force the multiply to take inputs of type decimal instead of whatever the type that is being used and converted to decimal.

Decimal.Multiply(decimal d1, decimal d2) and will enforce and output of type decimal. Where as the * you could do:

decimal result = yourDecimal * yourInt;  

This allows you to mix and match types in some cases and it will handle it all for you but the type is not guaranteed to be decimal depending on how the right side is defined.
