C++ Wiskunde
C++ Wiskunde
C++ het baie funksies wat jou toelaat om wiskundige take op getalle uit te voer.
Maks en min
Die funksie kan gebruik word om die hoogste waarde van x en
y te vind :max(x,y)
Voorbeeld
cout << max(5, 10);
En die funksie kan gebruik word om die laagste waarde van
x
en y te vind :min(x,y)
Voorbeeld
cout << min(5, 10);
C++ <cmath> Kopskrif
Ander funksies, soos sqrt
(vierkantswortel), round
(rond 'n getal) en log
(natuurlike logaritme), kan in die <cmath>
koplêer gevind word:
Voorbeeld
// Include the cmath library
#include <cmath>
cout <<
sqrt(64);
cout << round(2.6);
cout << log(2);
Ander wiskundige funksies
