Problems with 'HISTOGRAM'

[Martin Vissers <martin.vissers(at)users.whh.wau.nl>]

Dear newsreaders

I have a problem with the IDL fuction histogram.
I'm running IDL 5.0.3a on windows NT4.0 (sp5)

If I make the following histogram:

aa=histogram(dindgen(330)-180.0d,min=-180.0d,max=180.0d,binsize=10.0d)

the array aa has 37 elements:
AA              LONG      = Array[37]

but it should have 36 elements ??????

Anyone for an answer ??

Thanks

Martin
