Description

When a querying a decimal field in mysql passing a string representation of a float with more than 6000 characters, an exception occurs. 

DjangoModel.objects.filter(num_field__gte="1.000000000000000000000000000000000000000000.....")

_mysql_exceptions.Warning: Truncated incorrect DOUBLE value: '1.000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000'

As you add more characters mysql's performance seriously degrades.

"Doctor! It hurts when I do this" "Then stop doing that!"

Erm... yeah. Ok. Good to know, but I don't think we're going to try and fix this one. The official position on this bug is going to be "ah... don't do that".

I am, however, slightly intrigued at the kind of use case that requires 6000+ significant figure of floating point representation...
