What does INT(5) in mysql mean?

Question

I always thought INT(5) means a number which has a max size of 5 digits. I tried entering a huge number inside it and it somehow got cut down to 2147483647

This obvi

Answer 1

An int can be between -2147483648 and 2147483647 signed, or 0 and 4294967295 unsigned.

Thats why it was cut down to that if you entered a number larger than it as a signed value
