Note that those values are of type ‘float’, which is a distinct type
from ‘Decimal’ with very different behaviour.

You can write a function to do it.
Alternatively, this case seems simple enough that you can write a
generator expression. Assuming you want ‘Decimal’ values:
>>> from decimal import Decimal
>>> amounts = (Decimal(mantissa)/10 for mantissa in range(-105, 105))
>>> for amount in amounts:
... print amount
...
-10.5
-10.4
-10.3
-10.2
-10.1
-10
-9.9
…
9.6
9.7
9.8
9.9
10
10.1
10.2
10.3
10.4
