Type Conversion in Expressions

C#'s type promotion rules. Here is the algorithm that they define for binary operations: IF one operand is a decimal, THEN the other operand is promoted to decimal (unless it is of type float or double, in which case an error results). ELSE IF one operand is a double, the second is promoted to double. ELSE IF one operand is a float, the second is promoted to float. ELSE IF one operand is a ulong, the second is promoted to ulong (unless it is of type sbyte, short, int, or long, in which case an error results). ELSE IF one operand is a long, the second is promoted to long. ELSE IF one operand is a uint and the second is of type sbyte, short, or int, both are promoted to long. ELSE IF one operand is a uint, the second is promoted to uint. ELSE both operands are promoted to int.
