This problem persists since "years". Currently I have PMA 4.6.1. The values under the
SHOW TABLE STATUS
nijel posted my question as issue on github and he mentioned something regarding rounding problem.
I remembered that I have in my
php.ini this setting:
precision = 20
After playing around I found out that the value of
20 causes this issue. Up to the value
16 the size is displayed correctly. Above
16 the weird size output starts.
