in thread How to check if a variable's value is equal to a member of a list of values

This is an interesting point. Do you know what value is taken for the hash key? The string representation or the floating point binary representation?

When the first is true than what you said falls in the whole class of floating point related problems, e.g. equality of floats.

    Hash keys are always strings.
