LN2 | Returns the natural logarithm of 2 (approx. 0.693) |

LN10 | Returns the natural logarithm of 10 (approx. 2.302) |

LOG2E | Returns the base-2 logarithm of E (approx. 1.442) |

LOG10E | Returns the base-10 logarithm of E (approx. 0.434) |

PI | Returns PI (approx. 3.14) |

SQRT1_2 | Returns the square root of 1/2 (approx. 0.707) |

SQRT2 | Returns the square root of 2 (approx. 1.414) |

abs(x) | Returns the absolute value of x |

acos(x) | Returns the arccosine of x, in radians |

asin(x) | Returns the arcsine of x, in radians |

atan(x) | Returns the arctangent of x as a numeric value between -PI/2 and PI/2 radians |

atan2(y,x) | Returns the arctangent of the quotient of its arguments |

ceil(x) | Returns x, rounded upwards to the nearest integer |

cos(x) | Returns the cosine of x (x is in radians) |

exp(x) | Returns the value of Ex |

floor(x) | Returns x, rounded downwards to the nearest integer |

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

max(x,y,z,...,n) | Returns the number with the highest value |

min(x,y,z,...,n) | Returns the number with the lowest value |

pow(x,y) | Returns the value of x to the power of y |

random() | Returns a random number between 0 and 1 |

round(x) | Rounds x to the nearest integer |

sin(x) | Returns the sine of x (x is in radians) |

sqrt(x) | Returns the square root of x |

tan(x) | Returns the tangent of an angle |

## Example (BASIC)

Rem Math Example r = 42 Print Math.PI * Math.pow(r, 2)

## Example (JavaScript)

//Math Example r = 42; NSB.Print(Math.PI * Math.pow(r, 2));
