a b/c bug + ifactor bug
Hello,
I am new to this list, but I am an enthusiastic HP Prime user and I hope that they iron out all the early problems. I found two problems: 1. In Home mode, enter: 1.2+0i Then press a b/c > this cycles between 1.2, 6/5, and 1+(1+i)/5. Type or conversion problem between complex and real? 2. In CAS mode, start by entering: ifactor(2ˆ101+1003). Then enter: ifactor((2ˆ101+1001)*(largest factor of 2ˆ101+1003)) where "(largest factor of 2ˆ101+1003)" is replaced by its meaning. This returns a strange result: 1*177509...24691 The latter is the value of (2ˆ101+1001)*(largest factor of 2ˆ1001+1003). Peter

RE: a b/c: definitely a "display" bug. If you grab the erroneous expression from the history line, it becomes 1+1/5 and the "i" disappears.

Re: ifactor
Yep, also a problem   same with ifactors(your large composite) returns [1 1 177 . . . 1] The factor 1 seems to occur with integers greater than 10^32.
