IM 6.7.8.2 Q16 Mac OSX Snow Leopard

The following fx calculation does not seem to working with scientific notation. Correct me if I am wrong, but this was fixed some time ago. I assume it got lost somewhere along the way.

Fix -fx to interpret scientific notation properly.


val=2.44141e-05
convert xc: -format "%[fx:round(255*$val)]" info:
311

Should round to zero, right?

convert xc: -format "%[fx:round(255*2.44141e-05)]" info:
311

Right. A bug. Will have a fix within a day or two.

Thanks. It is fixed in IM 6.7.8.4 Q16 beta:


This works again.

imb convert xc: -format "%[fx:round(255*2.44141e-05)]" info:
0


This also works:

imb convert xc: -precision 10 -format "%[fx:1e+6]" info:
1000000
