Imaginary literals are described by the following lexical definitions:
imagnumber: (floatnumber | intpart) ("j"|"J")
An imaginary literal yields a complex number with a real part of
0.0. Complex numbers are represented as a pair of floating point
numbers and have the same restrictions on their range. To create a
complex number with a nonzero real part, add a floating point number
to it, e.g., (3+4j)
. Some examples of imaginary literals:
3.14j 10.j 10j .001j 1e100j 3.14e-10j
