When would someone use constexpr verse consteval?

You would use consteval to enforce compile-time evaluation. Calling consteval function with run-time arguments would result in compile error.
Constexpr functions can be used both with const expressions and run-time arguments.

16:40:19 From Gonzalo to Everyone:
	What is the oldest C++ version where all that is on your presentation is possible?
16:46:59 From BobF to Everyone:
	You have a partial single-phase V-I example in the slides, have you attempted to evaluate reactive and apparent power .... let alone for 3-phase systems?
16:47:59 From Raul Pando to Everyone:
	Based on your professional experience using embedded C++, do you tend to resort to the latest standard revision available where possible (c++23 these days?) or do you find yourself constrained by  other factors, such client build systems?
16:49:35 From BobF to Everyone:
	I'll download the slides again ... it was on the 'Expressive signal generator' slide
16:50:14 From David to Everyone:
	Have you compared GCC, IAR, CLANG, or Green Hills and if so can you share your experience?
16:53:41 From Raul Pando to Everyone:
	I think the signal structure was just an example to leverage some of the flexibilitity "modern" features (lambdas with sine & consine).
16:54:34 From David to Everyone:
	Thanks for a very interesting presentation!
16:56:22 From BobF to Everyone:
	Yes, SIN (voltage) / COS (current) graph, also on the 'constexpr - generate array' slide
16:56:45 From Lyden Smith to Everyone:
	Thank you Amar!
16:56:53 From Raul Pando to Everyone:
	Thank you Amar
16:58:15 From BobF to Everyone:
	Thanks Amar, well done!
16:59:09 From Cameron to Everyone:
	Thanks Amar
16:59:11 From Raul Pando to Everyone:
	Great advice
