Type error: the float function has at most one parameter (2 parameters given). TypeError: float() takes at most 1 argument (2 given) The float function cannot be converted in arbitrary binary like the int functionįor example, when trying to convert the binary number 11 to decimal floating point 3.0, an error is reported. Value error: cannot convert string '2a1' to floating point. ValueError: could not convert string to float: '2a1' > float(3.42)Įrror when a non-decimal string is used as an argument, exceeding a numeric character > float('2a1') It is also possible to convert floating-point points to floating-point points, which would not make any sense and would be error-free. In Python, the Boolean equals 1.0 and 0.0 in the calculation: > float(True) The point here it can not convert alphanumeric strings, in some cases if you are scraping data or something like 400, symbol is alphanumeric then it consider an string, if you try convert to float it display an error, i give you this example to show it only convert numbers to float, in this case i solved the problem like this data '400. The following example shows how to use the float() function from a Python script: print(float(1))Ĭonversion of decimal integers to decimal floating-point numbers > float(5)Ĭonversion of decimal strings to decimal floating-point points > float('24.5')Ĭonversion of Boolean values to floating-point numbers The following examples demonstrate how float() can be used.

Float() function is used to convert integers and strings to floating-point numbers.
