[Numpy-discussion] numerical noise for simple calcululations

hi all,
I need a good estimation of noise value for simple calculations.
I.e. when I calculate something like sin(15)+cos(80) I get a solution
with precision, for example, 1e-11.
I guess the precision depends on system arch, isn't it?
So what's the best way to estimate the value?
I guess here should be something like 10*numpy.machine_precision, isn't it?
Regards, D.
