For ordinary addition and subtraction operations, we will not explain them in detail here, as shown in the following example: mysql> SELECT 3+4; +-----+ | 3+4 | +-----+ | 7 | +-----+ 1 row in set (0.03 sec) CEIL and FLOORCEIL are rounded up. As long as there are decimal places, no matter how many, they will be entered directly. For example: mysql> SELECT CEIL(3.01); +----------------+ | CEIL(3.01) | +----------------+ | 4 | +----------

Introduction: For ordinary addition and subtraction operations, we will not explain them in detail here. For example: mysql> SELECT 3+4;+-----+| 3+4 |+ -----+| 7 |+-----+1 row in set (0.03 sec) CEIL and FLOORCEIL are rounded up. As long as there are decimal places, no matter how many, they are directly entered into one digit. For example: mysql> SELECT CEIL(3.01);
Introduction: Erlang operators (comparison operators, numerical operators, shift operators, logical operators). Erlang's comparison operator opDescription==equal/=not equal=less than or equal to less than=greater than or equal to greater than=:=exact equal to=/=exact equal to/=the difference between equal and exact equal: If you want to compare
