Python float to Decimal conversion

Question

Python Decimal doesn\'t support being constructed from float; it expects that you have to convert float to a string first.

This is very inconvenient since standard

Answer 1

The "official" string representation of a float is given by the repr() built-in:

>>> repr(1.5)
'1.5'
>>> repr(12345.678901234567890123456789)
'12345.678901234567'

You can use repr() instead of a formatted string, the result won't contain any unnecessary garbage.
