[Freeipa-devel] [PATCH] 192 Replace float with Decimal

[Martin Kosek]

This patch fixes RHEL 6.2 build issue.
----
Having float type as a base type for floating point parameter in
ipalib introduces several issues, e.g. problem with representation
or value comparison. Python language provides Decimal type which
help overcome these issue.

This patch replaces a float type with Decimal type in Float
parameter. A precision attribute was added to Float parameter that
can be used to limit a number of decimal places in parameter
representation. This approach fixes a problem with API.txt
validation where comparison of float values may fail on different
architectures due to float representation error.

In order to safely transfer the parameter value over RPC it is
being converted to string which is then converted back to Decimal
number on server side.
