Override range number buttons Many parameters have restricted ranges and if you input a value higher than the maximum, it'll snap back to the maximum value.

Examples include: 


speed in a fluid simulation is limited to 100.
energy of a lamp is limited to 10.
etc.


Is there any way to override these restrictions?
In short, there is no way to override internal limits.

However blender has 2 limits per setting:


soft-limits: which is for number button mouse motion
hard-limits: allow you to type in more extreme values, but there still is a limit.


These let you enter lamp energy of 10000000.0 for eg.
