The parseFloat in JavaScript:- Geniusofstudent

-
  • The parseFloat() function parses a string and returns a floating point number.
  • This function determines if the first character in the specified string is a number. If it is, it parses the string until it reaches the end of the number, and returns the number as a number, not as a string.
  • Only the first number in the string is returned.
  • If the first character cannot be converted to a number, parseFloat() returns NaN.
