Converts strings into floating point numbers.
The numstring argument is a string that contains a floating point number.
The parseFloat method returns an numerical value equal to the number contained in numstring. If no prefix of numstring can be successfully parsed into a floating point number, NaN (not a number) is returned.parseFloat("abc") // Returns NaN. parseFloat("1.2abc") // Returns 1.2.
You can test for NaN using the isNaN method.
