Return true if the specified floating point number has an indeterminate value, and false otherwise. An indeterminate floating‐point value ("quiet NaN" or "QNaN") results from an operation for which the result is not mathematically defined, such as multiplying infinity by zero. If a QNaN is used in a subsequent operations the result will also be a QNaN. Note that, because a QNaN is a NaN, if this method returns true, then isNan(x) will also return true.
