Create a complex number with the value \var{real} + \var{imag}*j or
convert a string or number to a complex number.
convert a string or number to a complex number. If the first
parameter is a string, it will be interpreted as a complex number
and the function must be called without a second parameter. The
second parameter can never be a string.
Each argument may be any numeric type (including complex).
If \var{imag} is omitted, it defaults to zero and the function
serves as a numeric conversion function like \function{int()},
\function{long()} and \function{float()}; in this case it also
accepts a string argument which should be a valid complex number.
