Circularity 1 or 0, where are middle values?

[Leonardo Schenkel]

I´ve downloaded some time ago version 1.36b.

Particle Analysis was only returning '1' or '0' on Circularity ratio.

Then on the release by the date of 2 july,i think its was 1.37h. The
circularity calculation became to behave properly (returning float values
ex: '0.2436')

Then on the latest release it started to return '0's and '1's again. no
intermediate values.

Any one got tips, or can reproduce this? (get some binary image with some
objects and run Analize Particles with circularity values on the result.)

Thanks,
Leo

I can reproduce this behavior by setting "Decimal Places" in the  
Analyze>Set Measurements dialog to 0.
