Converts String objects into floating point numbers.
parseFloat( numstring )The numstring argument is a String object that contains a floating point number.
The parseFloat function returns an numerical value equal to the number contained in numstring. If numstring cannot be successfully parsed into a floating point number, NaN (not a number) is returned.
You can test for NaN using the isNaN function.
