AIMAG Function
AIMAG Function
The AIMAG function returns the imaginary part of a complex number.
z
is a complex expression
Considerations
The AIMAG function returns the imaginary part of a complex number. Its type is always
real. That is, if
z = CMPLX (x, y)
then,
AIMAG (z) = y
Example of the AIMAG Function
In the following example, if the value (4E3,-2.1) is read into XNUMBER, the value -2.1
is stored in Y.
COMPLEX xnumber
READ (*, *) xnumber
y = AIMAG (xnumber)
AINT Function
The AINT function returns the non-fractional part of a number.
The table below shows the argument and function type of the AINT generic function
and of its associated specific function.
Considerations
•
The result type of the AINT function is the same as the type of its argument.
•
If the absolute value of x is less than 1.0, AINT returns zero.
