convert user input to Decimal objects using eval()?

[Julian Hernandez Gomez]

Hi !

This is maybe a silly question, but...

is there a "easy way" to make eval() convert all floating numbers to Decimal 
objects and return a Decimal?

for example:

eval('1.00000001+0.1111111') --> convert each number to a Decimal object, 
perform the sum and obtain a Decimal object as a result?

maybe a parser is needed, but eval() already do the job, but I need the 
precision that Decimal offers for numerical applications.

Thanks in advance.
