Hey!
I'm trying to get a grip of the Histogram function in IDL, but have
run into a problem that I don't understand. As you can see from the
code below I have created an array with six differend elements,but
when I call HISTOGRAM with a binsize equal to 0.1 then it seems like
1.2 and 1.3 is put in the same bin. Why is this?


IDL> arr = [1.1,1.2,1.3,1.4,1.5,1.6]
IDL> print, HISTOGRAM(FLOAT(arr), binsize=0.1)
1 2 1 1 1


Thanks!
Best regards Silje
