>> type(pi) A float value is only accurate upto 15 … These combinations of letters are used to represent invalid numbers (NaN) and infinity values (infinity or inf). Python int. Float method is part of python standard library which converts a number or a string containing numbers to a float data type. float is the keyword used to represent these floating point numbers. Otherwise, float_repr_style has value 'legacy' and repr(x) behaves in the same way as it did in versions of Python prior to 3.1. As a general rule, if you have an object in Python, and want to convert to that type of object, call type(my_object) on it. Output. Aug 22, 2020. The result is a float, but only quotient is considered and the decimal part or reminder is ignored. Python float variable Example. is_integer ()) # False f_i = 100.0 print ( f_i .
