What does the NaN function do?

[RH-Calvin]

The NaN property represents "Not-a-Number" value. This property indicates that a value is not a legal number. The NaN property is the same as the Number. Nan property. Tip: Use the isNaN() global function to check if a value is a NaN value.

NaN stands for 'not-a-number'. The function isNaN determines the argument or the value is a NaN. The function returns true if the argument is not a number, otherwise returns false

In computing, NaN, standing for not a number, is a member of a numeric data type that can be interpreted as a value that is undefined or unrepresentable, especially in floating-point arithmetic. Quiet NaNs are used to propagating errors resulting from invalid operations or values.
