MySQL returnerer ekstra poster, når du bruger et langt typenummer til at filtrere varchar-typen

I alle andre tilfælde sammenlignes argumenterne som flydende (reelle) tal. - https://dev.mysql.com/doc/ refman/5.7/da/type-conversion.html

for eksempel

drop procedure if exists p;
delimiter $$

create procedure p (inval float, inval2 float, inval3 float)
select inval,inval2,inval3;

call p(6011656821812318924,6011656821812318925,6011656821812318926);

+------------+------------+------------+
| inval      | inval2     | inval3     |
+------------+------------+------------+
| 6.01166e18 | 6.01166e18 | 6.01166e18 |
+------------+------------+------------+
