The last two statements display the results shown because 2 is equal to neither 1 nor 0. A small integer. A medium-sized integer. A normal-size integer. This type is a synonym for INT. A large integer. In this case, MySQL performs a string-to-number conversion that involves no intermediate double-precision representation.
This means that if you multiply two big integers or results from functions that return integers , you may get unexpected results when the result is larger than M is the total number of digits the precision and D is the number of digits after the decimal point the scale. The decimal point and for negative numbers the - sign are not counted in M.
If D is 0, values have no decimal point or fractional part. The maximum number of supported decimals D is If D is omitted, the default is 0. If M is omitted, the default is
