WINDOWS

Microsoft Project for Windows recognizes the presence of but makes limited use any math coprocessor (80X87). A math coprocessor is not necessary because the majority of all the calculations performed by Project deal with date manipulations, and dates are recognized internally as serial numbers.

Math coprocessors are used only in those cases where floating-point calculations are being made. Serial numbers are not floating point and, therefore, do not require the assistance of a coprocessor. All other calculations that are floating-point numbers will make use of (e.g. Actual Cost) a math co-procesor, if it is present. Otherwise, these values are calculated internally by Microsoft Project for Windows.
