Complex number in fortran 90

  1. May 17, 2015 #1
    i have a a little problem in fortan90 i just wanted to know how to input a complex number ( input real and img part alone ) all i want to do is to make a simple program about DeMoivres Theorem i have been around in google
    all i know how to declare a argument as complex
    complex a
    then how to let the user input the real and img part for argument a
    i did read(*,*)a
    every time it give runtime error :)
    thanks in advance

    A google search with fortran90 and complex returned quite a few links.

    In any case, if you want to read a complex number straight into variable 'a', for example, as you show above, you need to enter your value as a complex number, i.e., enclosed in parenthesis, in other words, you type, say, "(1.43, 22.3)"
