https://en.wikipedia.org/wiki/ANSI_escape_code goes a bit more in-depth.

> CSS should NOT be becoming turing complete. Nor any other DSL

Hasn't it been so for a while? I mean I agree with you but it's a bit late

I spent longer than I care to admit trying to find the player keys..

Excellent idea. I could see a scifi story based on that too.

This should help porting all the old Cobol and Perl apps out there, no?

ChatGPT 4 pondered for a while, then started "Analyzing..", and eventually "Finished analyzing" (all following verbatim output):

python 9999999999999999.0 - 9999999999999998.0 Result 2.0

The result of the calculation 9999999999999999.0−9999999999999998.0 is 2.0.

This result may seem counterintuitive, but it's due to how floating-point numbers are represented and handled in computing. Floating-point arithmetic can introduce small rounding errors, especially with very large numbers, as precision is limited. In this case, the precision required to represent these large numbers exactly is beyond what typical floating-point representations (like IEEE 754 double precision) can handle, leading to a slight error in the calculation.
