    or, if the OP happens to use Math::BigFloat

    It's interesting that Math::BigFloat decides it has to numify a non-numeric string to NaN ... when everything else numifies such a string to zero.

    Actually, I'm tempted to s/interesting/stupid/, but maybe there's a precedent somewhere that gives some credence to the Math::BigFloat behaviour.
