How to find angles, which lies between -π and -2π.Because matlab returns only values between ±π using atan or atand function.

Because matlab returns only values between ±π using 'atan' or 'atand 'functions.i want to get an angle between -π and -2π. Are there any solution to do that using functions? i'm finding a solution without using a absolute value(abs function)
thank you

Do this to your angle, 'a':
a = mod(a,pi)-2*pi;
It will then lie between -2*pi and -pi.
[Note: atan gives angles between -pi/2 and +pi/2, not -pi and +pi.]
