тестил такой код
program NewProject2121;
var a,b,c:real;
begin
a:=0.523;
b:=0.3214;
b:=a+b;
c:=acos(b);
drawText(''+c, 0, 0);
c:=acos(b);
drawText(''+c, 0, 20);
c:=acos(b);
drawText(''+c, 0, 40);
c:=acos(b);
drawText(''+c, 0, 60);
c:=acos(b);
drawText(''+c, 0, 80);
c:=acos(b);
drawText(''+c, 0, 100);
repaint;
delay(200000);
end.
на эмуле
на теле
и как ето понимать?
