I /think/ that what is happening there is that the displayed text => NaN is the result of ruby attempting to print the value of Float::NAN. There is no constant NaN, it is just text displayed when it tries to print the value of the Float constant Float::NAN. In other words Float::NAN is a constant which is not actually any number at all and when printed displays as NaN to show that it is not a number.
