    Resolved [RESOLVED] Math/stats question - Infinity / (1 + Infinity)

    I am using the Math.Exp function in a calculation, and the result essentially is Infinity / 1 + Infinity, which is 1 statistically, but it is showing as "NaN" (not a number). Is there a way to calculate/show the result of this as 1 (besides just testing for NaN and explicitly setting it as 1?)

    The equation simplifies as:

    Math.Exp(X) / (1 + Math.Exp(X))

    X is a number larger than 709.782712893 in order to get the NaN result.
