Math function example [Inbuilt]

//Prog:Example of Math Function

#include<math.h>
#include<stdio.h>
#include<conio.h>
void main()
{
int a=10;
float b=2.3;
printf("Log10:%f\n",log10(a));

printf("ceil 2.3:%f\n",ceil(b));
printf("floor 2.3:%f\n",floor(b));

printf("abs:%d\n",abs(a));
a=-1;
printf("abs:%d\n",abs(a));

a=90;
printf("tan:%f\n",tan(a));
printf("cos:%f\n",cos(a));
printf("sin:%f\n",sin(a));

printf("pow:%f\n",pow(4,2));

printf("exp(0)):%f\n",exp(0));
printf("exp(1)):%f\n",exp(1));

printf("sqrt:%f\n",sqrt(16));

b=-45.66;
printf("fabs:%f\n",fabs(b));
}

Above example shows how you can perform Maths(inbuilt) functions !
