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.
