Description:
hi,

i'm just studying mysql v5.7 for some characteristic on this version. And when i read the documentation, i found that the descriptions for the parameter "M" mismatched in different chapters:

1. in chapter 11(https://dev.mysql.com/doc/refman/5.7/en/data-types.html)，it says：
 
For integer types, M indicates the maximum display width. 

2. in chapter 11.1.1(https://dev.mysql.com/doc/refman/5.7/en/numeric-type-syntax.html), it is:

For integer data types, M indicates the minimum display width. 

so , my question is , what on earth M indicates? the "maximum" or the "minimum" display width?

pls kindly help confirm.

thanks.

How to repeat:
check and compare the following chapters for "M indicates":
https://dev.mysql.com/doc/refman/5.7/en/data-types.html
https://dev.mysql.com/doc/refman/5.7/en/numeric-type-syntax.html
