Fixes for Unresolved comment '# TODO: remove placeholding zeroed y' in sklbench\datasets\loaders.py:804 and Unresolved comment '# TODO: add float values'. in sklbench\utils\special_params.py:48

Description

Fixes in Unresolved comment '# TODO: remove placeholding zeroed y'. lines of code = 1 in sklbench\datasets\loaders.py:804

Originally it was like y = np.zeros((x.shape[0],))
Changed it to y = np.zeros(x.shape[0])

Fixes in Unresolved comment '# TODO: add float values'. lines of code = 1 in Found in [sklbench\utils\special_params.py:48]
I added a function in special_params.py called def float_range(start,stop,step) to accept float values
I tested it in Python:

import sklbench.utils.special_params as spl
spl.explain_range('[RANGE]add:1:5:1')
[1.0, 2.0, 3.0, 4.0, 5.0]
spl.explain_range('[RANGE]add:1.1:5.1:.2')
[1.1, 1.3, 1.5, 1.7, 1.9, 2.1, 2.3000000000000003, 2.5000000000000004, 2.7000000000000006, 2.900000000000001, 3.100000000000001, 3.300000000000001, 3.5000000000000013, 3.7000000000000015, 3.9000000000000017, 4.100000000000001, 4.300000000000002, 4.500000000000002, 4.700000000000002, 4.900000000000002, 5.100000000000002]
spl.explain_range('[RANGE]mul:1.1:5.1:.2')
However for the geometric progression, make sure the step value is greater than 1 as the result gets progressively smaller and will never converge. We can do a comparison for step size to be greater than 1 (currently not implemented)
spl.explain_range('[RANGE]mul:1.1:5.1:2')
[1.1, 2.2, 4.4]
spl.explain_range('[RANGE]pow:1.1:5.1:2')
[]
spl.explain_range('[RANGE]pow:1.1:10:2')
[]
spl.explain_range('[RANGE]pow:0.2:1.1:5.1:2')
