float()
The built-in float()
function returns a float value based on a string, numeric data type, or no value at all.
Syntax
float(num_string)
The num_string
parameter is optional and should either be a string or numeric type.
Example
In the example, the float()
function is used to return float-type versions of an integer value 314
and a string “314”:
print(float(314))print(float("314"))
The following output will look like this:
314.0314.0
