Regression in numerical evaluation

Comment on this YouTube video:

Your current method can achieve this,
but in the segment from 0:23 to 0:26 in that video,
your input sequence is:

1. 118
2. ENTER
3. 48
4. ENTER
5. F ['()]
6. C [√x]
7. 2
   8 ENTER
8. x
9. −
10. C [√x]

At this point, the screen can display √(118 − 48√2).

However, on my DB50X it does not display like this; instead, it shows √50.117749.

By the way, the calculator model I’m using is the DM42N, and the firmware version is 0.9.15 “Myriam” (db50x-dm42n-firmware).

(Confirmed regression)
