Error on displaying z1+1*z2 for complex numbers z1 and z2 #208

Closed BillFoster closed 11 years ago

BillFoster commented 12 years ago

See http://tallaght.ncl.ac.uk/question/325/testcx/

We see that, for example, 1+i +1*(-2+2i) is displayed in the gapfill as 1+i-2-2i. For some reason the 2i is displayed as -2i

Still getting the same display problem in http://tallaght.ncl.ac.uk/numbas-previews/45183d34-4ed2-4c4d-8885-a8b3b79bb22c/index.html

Ah! The hack I made to fix the SCORM manifest problem is stopping git from updating the servers. Hang on a bit...

christianp commented 12 years ago

Should be OK now.

as in the first comment.

christianp commented 11 years ago

It seems to be working for me now. Can you check?

BillFoster commented 11 years ago

Still the same problem, with s=1 in testcx http://tallaght.ncl.ac.uk/question/325/testcx/

(s had been changed to s=-1 which works OK, but not s=1)
