Formatting Complex Numbers


For a project in one of my classes we have to output numbers up to five decimal places.It is possible that the output will be a complex number and I am unable to figure out how to output a complex number with five decimal places. For floats I know it is just:

print "%0.5f"%variable_name

Is there something similar for complex numbers?


Solution

  • For questions like this, the Python documentation should be your first stop. Specifically, have a look at the section on string formatting. It lists all the string format codes; there isn't one for complex numbers.

    What you can do is format the real and imaginary parts of the number separately, using x.real and x.imag, and print it out in a + bi form.
