1. ## ROM 2.09 - Solve Equation Problem

Hi,

This is a comparison with same flags between 49G (1.19-6) and 50g
(2.09)
Assume default values...

1. Enter to NUM.SLV
2. Select Solve equation..
3. Enter Eq: 'dX(X^2+3*X)=0'

d is the symbol [RS][T]

4. Select X and press [SOLVE]
5. Press ON to exit

At this point level 1 shows X-1.5); now, this is the problem:

6. Replace the value for X=-1.2
7. Enter again to NUM.SLV and select 1
8. Select X (that shows -1.2) and press [SOLVE]

49G gets X:-1.5 --> OK
50g gets X:-1.200001 --> ??

Any ides for this peculiar result?... maybe the solution is PURGE
variable but no coincidence for both models (or ROM)?

Well, transfer 2.09 (via ROMUPLOAD) into 49G,
and results might then be the same (both wrong

It's just like politics -- as long as both parties voted for it
(or continued similar policies), it must have been good for the country,
even at a cost of \$1,000,000,000,000 or so (and so many lives, etc.)

2: Enter Eq: 'dX(X^2+3*X)=0'
1: Enter 'X'
Enter ZEROS
OK

The solution is OK but, the problem is with Equation Solver, ROM 2.09
(and similar).
This is a bug?...
