## C Math Functions

The following are the list of inbuilt math functions in c programming.

Functions | Explanation |
---|---|

abs(x) | Returns the absolute value of x (for integer type numbers). |

acos(x) | Returns the arc-cosine of x. |

acosh(x) | Returns the hyperbolic arc-cosine of x. |

asin(x) | Returns the arc-sine of x. |

asinh(x) | Returns the hyperbolic arc-sine of x. |

atan2(y, x) | Returns the angle in the plane between the positive x-axis and the ray from (0, 0) to the point (x, y), for atan2(y, x). |

atan(x) | Returns the arc-tangent (in radians) of x. |

atanh(x) | Returns the hyperbolic arc-tangent of x. |

cbrt(x) | Returns the cube root of x. |

ceil(x) | Returns a number representing the nearest integer which is greater than or equal to x. |

frexp(x, e) | Returns the mantissa and the exponent of x. |

hypot(a, b) | Returns the square root of the sum of squares of its arguments. |

ldexp(x, e) | Returns x multiplied by 2 raised to the power of exponent. |

log10(x) | Returns the base 10 logarithm of x. |

log(x) | Returns the natural logarithm (base E) of x. |

modf(x, intpart) | Breaks the given argument into two parts, one is integer and the other one is fractional. |

pow(base, exponent) | Returns a number representing the given base taken to the power of the given exponent. |

round(x) | Returns the value of a number rounded to the nearest integer. |
