'How to divide by infinity in MathCAD

Could anyone recommend a proper way to work with infinite values in MathCAD? For example when calculating resistances. If I use the infinity constant I get a floating point error.

w := 314.159 s^-1
C := \infinity F

X.C := 1/wC

I have to use large value for the C (10^10) and cope with the X.C being small and not exactly zero.

I think the Infinit is symbolic concept. Try to use symbolic calculations like that:

In my practice if I know that number may be too small I add TOL to it.
