MulDiv
The MulDiv
function multiplies two 32-bit values and then divides the 64-bit result by a
third 32-bit value. The return value is rounded up or down to the nearest
integer.
int MulDiv(
|
int nNumber, |
// 32-bit signed
multiplicand |
|
int nNumerator, |
// 32-bit signed
multiplier |
|
int nDenominator |
// 32-bit signed
divisor |
|
); |

Parameters
nNumber
Specifies the
multiplicand.
nNumerator
Specifies the
multiplier.
nDenominator
Specifies the
number by which the result of the multiplication (nNumber * nNumerator)
is to be divided.
Return Values
If the
function succeeds, the return value is the result of the multiplication and
division. If either an overflow occurred or nDenominator was 0, the
return value is -1.
