Exemple
Voici un exemple montrant une utilisation plus classique de cette fonction :
- SELECT "mod(-81,9)=" As Text, mod(-81,9) AS Result UNION
- SELECT "mod(15,3) = " As Text,mod(15,3) As Result UNION
- SELECT "mod(16,3) = " As Text, mod(16,3) AS Result UNION
- SELECT "mod(16.9,3) = " As Text,mod(16.9,3) As Result UNION
- SELECT "mod(16.8,3) = " As Text,mod(16.8,3) As Result UNION
- SELECT "mod(16.7,3) = " As Text,mod(16.7,3) As Result UNION
- SELECT "mod(16.6,3) = " As Text,mod(16.6,3) As Result UNION
- SELECT "mod(16.5,3) = " As Text,mod(16.5,3) As Result UNION
- SELECT "mod(16.4,3) = " As Text,mod(16.4,3) As Result UNION
- SELECT "mod(16.3,3) = " As Text,mod(16.3,3) As Result UNION
- SELECT "mod(16.2,3) = " As Text,mod(16.2,3) As Result UNION
- SELECT "mod(16.1,3) = " As Text,mod(16.1,3) As Result UNION
- SELECT "mod(17,3) = " As Text,mod(17,3) As Result UNION
- SELECT "mod(18,3) = " As Text,mod(18,3) As Result UNION
- SELECT "mod(19,3) = " As Text,mod(19,3) As Result UNION
- SELECT "mod(0,1) = " As Text,mod(0,1) As Result
on obtiendra le résultat suivant :
| Text | Result |
| mod(-81,9)= | 0.0 |
| mod(15,3) = | 0.0 |
| mod(16,3) = | 1.0 |
| mod(16.9,3) = | 1.9 |
| mod(16.8,3) = | 1.8 |
| mod(16.7,3) = | 1.7 |
| mod(16.6,3) = | 1.6 |
| mod(16.5,3) = | 1.5 |
| mod(16.4,3) = | 1.4 |
| mod(16.3,3) = | 1.3 |
| mod(16.2,3) = | 1.2 |
| mod(16.1,3) = | 1.1 |
| mod(17,3) = | 2.0 |
| mod(18,3) = | 0.0 |
| mod(19,3) = | 1.0 |
| mod(0,1) = | 0.0 |
