A complex constant approximates the value of a
mathematical complex number. The constant is a pair of real or
integer values, separated by a comma, and enclosed in parentheses.
The first constant represents the real part of that number; the
second constant represents the imaginary part.
The following is the general form of a complex constant:
- (c,c)
- c
Is as follows:
- For COMPLEX(4) constants, c is an integer or REAL(4)
constant.
- For COMPLEX(8) constants,
c is an integer, REAL(4) constant, or DOUBLE PRECISION
(REAL(8)) constant. At least one of the pair must be DOUBLE
PRECISION.
- For COMPLEX(16) constants (VMS, U*X),
c is an integer, REAL(4) constant, REAL(8) constant, or REAL(16)
constant. At least one of the pair must be a REAL(16) constant.
Note that the comma and parentheses are required.
