# C Math

C Programming allows us to perform mathematical operations through the functions defined in <math.h> header file. The <math.h> header file contains various methods for performing mathematical operations such as sqrt(), pow(), ceil(), floor() etc.

## C Math Functions

There are various methods in math.h header file. The commonly used functions of math.h header file are given below.

No. | Function | Description |
---|---|---|

1) | ceil(number) | rounds up the given number. It returns the integer value which is greater than or equal to given number. |

2) | floor(number) | rounds down the given number. It returns the integer value which is less than or equal to given number. |

3) | sqrt(number) | returns the square root of given number. |

4) | pow(base, exponent) | returns the power of given number. |

5) | abs(number) | returns the absolute value of given number. |

### C Math Example
