Weird Floating-Point Numbers: Infinity, Denormal, and NaN

WebMar 30, 2024 · Float () is a method that returns a floating-point number for a provided number or string. Float () returns the value based on the argument or parameter value that is being passed to it. If no value or blank parameter is passed, it will return the values 0.0 as the floating-point output. WebThe float () method returns a floating point number from a number or a string.
