Yes, it does - and help(abs) will tell you so in the next
Not abs(), but Mod(). See ?complex.

?complex reveals "Mod":

p.s. help.search("complex") reveals "complex", etc.

abs(1+1i) = 1.414214

Hi!
I want o calc the norm of a complex number ( |c| where c is complex). Does the
function abs() this ?
Thanks,
