MulDiv

Name:
MulDiv
Syntax:
INTEGER MulDiv(INTEGER VAL1, INTEGER VAL2, INTEGER VAL3)
Description:
Computes the result (VAL1 * VAL2)/VAL3.
Parameters:
VAL1, VAL2, and VAL3 are INTEGER values.
Return Value:
A 16-bit integer is returned based on the above equation. The arithmetic operations
are performed using unsigned arithmetic. Note that 32-bit math is used internally, so
that if VAL1*VAL2 is greater than a 16-bit number, accuracy is maintained. If the
final result is greater than 16-bits, the lower 16-bits are returned.
Example:
INTEGER X, Y;
FUNCTION MAIN()
{
X = 1970;
Y = 40;
PRINT("The result of (%d * %d)/25 = %d\n", X, Y,
MULDIV(X, Y, 25);
}
The PRINT statement would show the result as being 3152. In this case, X*Y is
greater than a 16-bit number, but accuracy is maintained due to the use of 32-bit
arithmetic internally.
