Fn.SetAccuracy

Set the default accuracy.

Syntax

Fn.SetAccuracy(N:INT):NULL

Description

N must be positive. An accracy of N means that all results X are rounded

such that | X - TrueValue | <= 0.5*10^(-N).

By default, the accuracy is set to 10.

  • @param N the accuracy to be set.

Example

Fn.SetAccuracy(10);
X1 := Fn.Sin(1);
Fn.SetAccuracy(30);
X2 := Fn.Sin(1);
Dec(X1, 100);
Dec(X2, 100);
