Operators inside complex expressions

[Daniel J S. <dan...@ie...>]

Shouldn't operators work inside complex numbers?  For example

gnuplot> print 2**31-1
2147483647.0
gnuplot> print {2**31-1,1}
               ^
         invalid complex constant

No.  Operators never work inside numbers.  Gnuplot's {a,b} syntax is for 
complex numbers, not complex expressions.

The way of getting that is

	print 2**31-1 + {0,1}

Most people would probably want to define

	i={0,1}

somewhere and then write

	print 2**31-1 + 1*i

Easy enough.
