Rational parameter values should be displayed as entered

[denkv]

Description

Experiment results show a different parameter value compared to what user entered.

Reproducability

User enters a float like "0.1" as a parameter value.
Experiment results show "0.10000000000000000555".

Expected behavior

We display what user entered.

Maybe in this particular case it is enough if we sensibly round float values and show an actually stored value in a tooltip (<abbr>). It is however unclear which value is stored and whether it is malformed on a way to the client: query example.
