principal value of ARG(z=x+y*i) - Hewlett Packard

This is a discussion on principal value of ARG(z=x+y*i) - Hewlett Packard ; Why HP 50g uses this definition of principal value of ARG(z) of a complex number z: (ARG(z=x+y*i)-> ATAN(y/x)+(1-x/ABS(x))*pi/2? -pi http://en.wikipedia.org/wiki/Complex_number Ex. ARG(-1-1*i)=(5/4)*pi instead of -(3/4)*pi Greetings, Simone....

Thread: principal value of ARG(z=x+y*i)

  1. principal value of ARG(z=x+y*i)

    Why HP 50g uses this definition of principal value of ARG(z) of a
    complex number z: (ARG(z=x+y*i)-> ATAN(y/x)+(1-x/ABS(x))*pi/2?

    -pi http://en.wikipedia.org/wiki/Complex_number

    Ex. ARG(-1-1*i)=(5/4)*pi instead of -(3/4)*pi
