Here are some more:

0.5  # one half
0.25  # one quarter
7.5  # seven and a quarter
0.001  # one thousandth

12345.6789
# twelve thousand, three hundred and forty-five, point six seven eight nine

-1.75  # minus one point seven five
0.0  # zero
3.0  # three

1.23e45  # one point two three times ten to the power of forty-five
