Numbers in C++
Following a simple example to show few of the mathematical operations on C++ numbers:
#include<iostream>
#include<cmath>
usingnamespacestd;
int main ()
{
// number definition:
short s=10;
inti=-1000;
long l =100000;
float f=230.47;
double d =200.374;
// mathematical operations;
cout<<“sin(d) :”<< sin(d)<<endl;
cout<<“abs(i) :”<< abs(i)<<endl;
cout<<“floor(d) :”<< floor(d)<<endl;
cout<<“sqrt(f) :”<<sqrt(f)<<endl;
cout<<“pow( d, 2) :”<< pow(d,2)<<endl;
return0;
}
