The framework includes a set of already implemented functions.

It also includes other general purpose ones.

Name | Description | Usage | Result |
---|---|---|---|

Abs |
Returns the absolute value of a specified number. | Abs(-1) | 1M |

Acos |
Returns the angle whose cosine is the specified number. | Acos(1) | 0d |

Asin |
Returns the angle whose sine is the specified number. | Asin(0) | 0d |

Atan |
Returns the angle whose tangent is the specified number. | Atan(0) | 0d |

Ceiling |
Returns the smallest integer greater than or equal to the specified number. | Ceiling(1.5) | 2d |

Cos |
Returns the cosine of the specified angle. | Cos(0) | 1d |

Exp |
Returns e raised to the specified power. | Exp(0) | 1d |

Floor |
Returns the largest integer less than or equal to the specified number. | Floor(1.5) | 1d |

IEEERemainder |
Returns the remainder resulting from the division of a specified number by another specified number. | IEEERemainder(3, 2) | -1d |

Log |
Returns the logarithm of a specified number. | Log(1, 10) | 0d |

Log10 |
Returns the base 10 logarithm of a specified number. | Log10(1) | 0d |

Returns the larger of two specified numbers. | Max(1, 2) | 2 |

Min |
Returns the smaller of two numbers. | Min(1, 2) | 1 |

Pow |
Returns a specified number raised to the specified power. | Pow(3, 2) | 9d |

Round |
Rounds a value to the nearest integer or specified number of decimal places. The mid number behaviour can be changed by using EvaluateOption.RoundAwayFromZero during construction of the Expression object. | Round(3.222, 2) | 3.22d |

Sign |
Returns a value indicating the sign of a number. | Sign(-10) | -1 |

Truncate |
Calculates the integral part of a number. | Truncate(1.7) | 1 |

It also includes other general purpose ones.

Name | Description | Usage | Result |
---|---|---|---|

in |
Returns whether an element is in a set of values. | in(1 + 1, 1, 2, 3) | true |

if |
Returns a value based on a condition. | if(3 % 2 = 1, 'value is true', 'value is false') | 'value is true' |

I just downloaded NCalc and tried it. It's awesome! I'm using it to implement numerical integration, where the user can enter the integrand as a function of x. I'm just doing this for a brown-bag demo, so I'm not doing anything particularly sophisticated. You are!
