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"))
