This article is about a function from ApCoCoA-1.

Fn.ArcCosN

Returns the arccosine of a given value with a given accuracy.

Syntax

Fn.ArcCosN(Val:RAT,Acc:INT):RAT

Description

This function returns the arccosine of Val rounded to the given

accuracy Acc. The domain of this functions ranges between -1

and 1.

  • @param Val Value of which to compute the arccosine.

  • @param Acc The desired accuracy.

  • @return The arccosine of Val rounded to the given accuracy Acc.

Example

R := Fn.ArcCosN(1/2, 30);
Dec(R, 40);
