If your master is clipping, will putting a gain plugin to reduce volume stop it clipping?

isn`t there also this thing with lowering the bit resolution when lowering the master fader? somebody told me about, but am not quite sure..anyone knows?

My understanding of the way 32-bit (float) audio works is that - in binary mathematical terms - each data word is split up into a sign bit (to indicate positive or negative), an exponent, and a mantissa which is raised to the exponent. Something like a a 24-bit audio sample with an 8-bit gain factor. This means that whatever the gain factor (ie. wherever in the range of -oo to 1500dB, ie. however loud the signal is), the data is still represented at 24-bit resolution. It is this which allows you to perform large changes of gain without reducing the de facto bit-depth of the output signal.
In the words of Wikipedia, " the benefit comes in the increased accuracy of low values. In floating point representation, the space between any two adjacent values is of the same proportion as the space between any other two adjacent values, whereas in an integer representation, the space between adjacent values gets larger in proportion to low-level signals. This greatly increases the SNR because the accuracy of a high-level signal will be the same as the accuracy of an identical signal at a lower level."

I disagree with that theory 
It might reduce the Signal-to-noise ratio but (it really has almost no impact on it in my opinion) as you can't hear it with a loud almost constant music(signal) as psytrance.
As to bits it does not reduce the bit deph it just doesn't make sense.

Bits are the dots that connect the wave. So i don't know make your own conclusion and tell us. I'm not going to count bits i'll trust my instinct that tells me it logicaly doesn't.

That is for clipping. No reason to clip. No reason to use a limiter to avoid(unless you really have to not by default) .
I clipped single mixer channels and they are clipping without the master going anywhere near 0dbfs and had awesome distortion.
I had internal clipping inside plugins such as compressors and eqs and all the rest. And sometimes it actualy sounds "good" or better for some sounds.
I would avoid it at all cost in the analog domain as it fries the equipment and in digital cause it sounds really bad in 90% of the cases.
Sometimes i peak at -6db sometimes at -3db that actualy does not mean anything as it is only the peak value. You can make a lousy mix peaking at -6db  sorry for english

It really is quite simple! Digital audio has rules and by far most of them are set in stone. No need for heavy theory nor arguing about who knows more about what.
Don´t touch the bloody ceiling is all!!!!!
No magic device,button nor hamster will unclip sound once it´s been done. Congratulations you made sausage.
The real question here is: Is it audible and does it get in the way of reproduction. There is a hell of a lot of "commercial" music that is effectively clipped and sounds like it too, but not all clipping is directly detrimental (just really bad practice technically)3
Since most people under 30 have grown up with that sound, it seems to be the accepted norm, so what do i know.
I remember some engineers from TC Electronic doing a test in house and found out that their younger employees could not recognize transients in music simply because they were used to hearing super compressed "modern" stuff.
