[New-bugs-announce] [issue17149] random.vonmisesvariate() returns a value only on the half-circle

[Serhiy Storchaka]

New submission from Serhiy Storchaka:

random.vonmisesvariate(mu, kappa) returns a value in the range (mu%2pi)-pi/2 to (mu%2pi)+pi/2 for kappa > 1e-6. For kappa <= 1e-6 it returns an uniform random value over the range 0 to 2*pi.
