Fix for bug #28121 "INSERT or UPDATE into DOUBLE(200,0) field being truncated to 31 digits"

Browse Source 
When storing a large number to a FLOAT or DOUBLE field with fixed length, it could be incorrectly truncated if the field's length was greater than 31.

This patch also does some code cleanups to be able to reuse code which is common between Field_float::store() and Field_double::store().
