Here is another variant using two equations with different sets of data:

Code:


A001 LBL A
A002 1
A003 STO A
A004 2
A005 STO B
A006 3
A007 STO C
A008 156.25
A009 STO X
A010 208.333333334
A011 STO R
A012 1.77951304201
A013 STO Q
A014 -R*X/(X*Q-R)
A015 -A*B/(B*C-A)
A016 RTN

The second equation yields 1.426E-3 while it should be -0.4.
The problem disappears if a simpler second equation is used (e.g. just A+B*C).

BTW.: The HP 33s has the same bug, but the results are different.

Edit: The different result was due to a wrong formula...
