Hi @Blake-Madden , thank you so much for creating an advanced version of Tinyexpr. I compared it to other libs and it has more and better features. Want to let you know that I'm using it successfully with Arduino Framework, but I had to downgrade the random generator since ESP32 microcontrollers don't support the entropy device. It would be nice whether you could define a condition to disable it. This is my patch:

static te_type te_random() { // std::random_device rdev; // std::mt19937 gen(rdev()); // std::uniform_real_distribution<te_type> distr(0, 1); // return distr(gen); return (double) rand() / RAND_MAX; // Generate a random double between 0 and 1 }

Cheers!

Of course, and thanks for the research on this. I'll wrap the mersenne twister code in one define block and an alternative rand() branch in another define block.

I'll seed rand() with time; let me know if that would be a problem.

I'll try to get to this this weekend.

I just checked in a change. If you define TE_RAND_SEED_TIME then it will use time instead of std::random_device. Let me know if this works OK with your platform.
