Hi,

Is it possible to "force" Gretl to show/compute simply a "0" instead of a "1.1102e-16"?

For example, in the script below the d series holds, in theory, nothing else but 0-s but in practice it still holds some kinds of "1.1e-17" numbers

nulldata 100

genr x=normal(0,1)

genr f=1/(1+exp(-x))

genr g=exp(x)/(1+exp(x)) # f = g

genr d=f-g # should be a series of 0

print d

summary d

Best,

Artur
