Hi David,

MulDiv, as, for example the Windows API function,
"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."
So the intermediate product has double the precision of the original
arguments.
There would still be a case to have a MulDiv in XSLT/XPath for SVG
applications.
Hard-core GUI developers use it all the time.
