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.

Nostalgia .Net |
|
.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
