Hi everybody - my first post here...Raw Message

At the moment I am spending some time with fpc's numlib and writing a

wrapper for a more versatile fitting procedure. Are there any problems

to add the unit math to the uses clause of some numlib units? I want to

use the value NaN (not-a-number) which is defined in numlib, but there

is no way to check whether a value is "equal" to NaN. In math, however,

there is a function IsNaN(). And my feeling is that these special

numbers NaN and Infinity are implemented in math in a more general way

than in numlib. An idea would be to remove NaN and Infinity from the

numlib unit "typ" to replace them by the math values.

Werner
