Rekenen in PHP
De variabele $getal heeft waarde: 36
Eenvoudig.
| $getal + 11; | echo $getal | ==> | 47 |
| $getal - 8; | echo $getal | ==> | 28 |
| $getal * 5; | echo $getal | ==> | 180 |
| $getal / 13; | echo $getal | ==> | 2.7692307692308 |
| $getal % 7; | echo $getal | ==> | 1 (Rest na deling door 7) |
Snelle rekenkunde
| $getal ++; | verhoogd met 1 | ==> | 37 |
| $getal --; | verlaagd met 1 | ==> | 35 |
| $getal+=21; | echo $getal | ==> | 57 |
| $getal-=15; | echo $getal | ==> | 21 |
| $getal*=4; | echo $getal | ==> | 144 |
| $getal/=9; | echo $getal | ==> | 4 |
Machten en wortels
| 363; | pow ($getal,3) | ==> | 46656 |
| wortel(36); | sqrt ($getal) | ==> | 6 |
| 5de macht wortel(36); | pow ($getal , 1/5) | ==> | 2.048 |
| absoluut | abs(-12) | 12 |
