## Fn.CosN

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

### Syntax

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

### Description

This function returns the cosine of `Val` rounded to the given

accuracy `Acc`.

@param

*Val*Value of which to compute the cosine.@param

*Acc*The desired accuracy.@return The cosine of

`Val`rounded to the given accuracy`Acc`.

#### Example

R := Fn.CosN(1, 30); Dec(R, 40); 0.540302305868139717400936607443 -------------------------------
