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); 0.8414709848 ------------------------------- 0.84147098480789650665250232163 -------------------------------
