[GRASS-user] Complex numbers in GRASS

GRASS GRASS user

Hi List,

I understand it may sound kind of strange problem.
I need to know how GRASS manages complex numbers in a map.
I.e. i produced a map with r.mapcalc using a formula and in some cell I could have complex.
In GRASS i have not. I tried the same formula in MATLAB and I have, but MATLAB manages complex as i can select the real part of a complex with real_part=real(number).
Is there in GRASS anything similar?

Thank you in advance

r.mapcalc doesn't understand complex numbers, only real numbers and
integers.
