point.comC Math Function
All the C program inbuilt functions which are declared in math.h header file. ‘Math.h’ header files support for all the mathematical related functions in C programming language.
| floor() | This function gives the nearest integer which is less than or equal to the argument passed to this function. |
| round() | This function gives the nearest integer value of the float/ double/ long double argument passed to this function. |
| ceil() | This function gives the nearest integer value which is greater than or equal to the argument passed to this function. |
| sin() | This function is used to calculate the sine value. |
| cos() | The cos( ) function is used to calculate the cosine. |
| cosh() | The cosh( ) function is used to calculate the hyperbolic cosine. |
| exp() | This function is used to calculate an exponential “e” to the nth power. |
| tan() | The tan( ) function is used to calculate the tangent. |
| tanh() | The tanh( ) function is used to calculate the hyperbolic tangent. |
| sinh() | The sinh( ) function is used to calculate the hyperbolic sine. |
| log() | It is used to calculates the natural logarithm. |
| sqrt() | It is used to find the square root of the argument passed to this function. |
| pow() | The pow() function is used to find the power of the given number. |
| trunc() | This function truncates the decimal value from the floating point value and returns an integer value. |
Example:
#include<stdio.h>
#include<math.h>
void main(){
printf("\n%f",ceil(3.3));
printf("\n%f",floor(3.2));
printf("\n%f",sqrt(7));
printf("\n%f",pow(2,4));
printf("\n%f",trunc(3.9));
printf("\n%f",tan(7));
printf("\n%f",tanh(2));
printf("\n%f",exp(3.1));
