7.19.7 parseFloat Method

Converts strings into floating point numbers.
Syntax
parseFloat(numstring)
Arguments
- numstring
- A string that contains a floating point number.
Remarks
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.
