Math Functions in C
Overview
Math functions in C provide a wide range of capabilities for performing mathematical operations. These functions, defined in the <math.h> header file, allow you to work with various mathematical operations, including basic arithmetic, trigonometry, logarithms, and more. Here's an overview of some commonly used math functions in C:
1. Basic Arithmetic Functions
a. add (Addition):
Adds two numbers.
#include <math.h> double add(double x, double y);
b. subtract (Subtraction):
Subtracts one number from another.
#include <math.h> double subtract(double x, double y);
c. multiply (Multiplication):
Multiplies two numbers.
#include <math.h> double multiply(double x, double y);
d. divide (Division):
Divides one number by another.
#include <math.h> double divide(double x, double y);
2. Trigonometric Functions
a. sin (Sine):
Calculates the sine of an angle (in radians).
#include <math.h> double sin(double x);
b. cos (Cosine):
Calculates the cosine of an angle (in radians).
#include <math.h> double cos(double x);
c. tan (Tangent):
Calculates the tangent of an angle (in radians).
#include <math.h> double tan(double x);
3. Exponential and Logarithmic Functions
a. exp (Exponential):
Calculates the exponential value of a number.
#include <math.h> double exp(double x);
b. log (Natural Logarithm):
Calculates the natural logarithm of a number.
#include <math.h> double log(double x);
c. pow (Power):
Raises a number to the power of another.
#include <math.h> double pow(double x, double y);
4. Rounding Functions
a. ceil (Ceiling):
Rounds a floating-point number up to the nearest integer.
#include <math.h> double ceil(double x);
b. floor (Floor):
Rounds a floating-point number down to the nearest integer.
#include <math.h> double floor(double x);
These are just a few examples of the many math functions available in C. Incorporating these functions into your programs enables you to perform a wide range of mathematical calculations.
