What is the Python float() method?
The Python float() function is a built-in Python function that converts the given value (number or string) into a floating-point number and returns the result. If the float() method fails to convert string to float then it raises the ValueError.
The Syntax of float() is:
float(Parameter value)
Parameter Value:
A number or a string that can be converted into a floating-point number.
Parameter is optional. If there is no parameter then it returns 0.0.
Note: If the value is a string then it should contain a decimal point and the valid argument should contain some numeric value.
Return Values
The float() function returns a floating-point value equivalent to the number passed as is or in the form of a string.
Errors
This method raises exceptions when it receives invalid parameter value.
