"float" values can be specified using "float" literals or the float() conversion function as shown in this tutorial:

1. "float" literals in scientific notations as shown below:

>>> 3.14159
3.14159
>>> -2.14
-2.14
>>> 2.99792458E8
299792458.0
>>> 9.4607E15
9460700000000000.0

2. float() function converting other data types to "float":

>>> float(1234)
1234.0
>>> float(True)
1.0
>>> float(False)
0.0
>>> float("3.14159")
3.14159
