Routines / Multiplying 32-bit values

LongMul
You can use the LongMul procedure to multiply two 32-bit quantities and obtain a 64-bit quantity.
Procedure LongMul (a, b: LongInt; VAR result: Int64Bit);
a
The first operand, which is a variable of type LongInt.
b
The second operand, which is a variable of type LongInt.
result
A pointer to the returned value.

DESCRIPTION
Given two variables of type LongInt, the LongMul procedure multiplies the two variables specified in parameter a and b, and returns the value in the variable specified by the result parameter.
