And in fact cos(Pi) is not, as you say, "-1 as it should be" but rather a real number close to -1:
? cos(Pi) %1 = -1.000000000000000000000000000 ? cos(Pi)+1 %2 = 1.2744735289059618216 E-57 ? --walter neumann On Thu, 30 Jun 2005, Sascha Rissel wrote:
Hello, I have a qustion about the sin(x)-function.Why is cos(Pi) = -1 as it should be, but sin(Pi) = -5.04870979 E-29 and not exactly 0?Other values of sin(x) are also a bit "out of place"... Regards, Sascha Rissel.
