I suggest to deactivate float in future LUA versions.

There are side effects like the issue with "string.format".

Integer calculation in older programs doesn't work any more.
- float enabled 600 / 70 = 8.571428571
- float disabled 600 / 70 = 8

There could be more undiscovered issues.

What do you think?

I'm against it. If not rise significantly memory requirements of programs, so it is clearly beneficial. I even edited the first program for FP.

have you tried building nodemcu from source after the 27th, as there's now a LUA_NUMBER_INTEGRAL macro to disable floats at compile time, and also a string.format() fix:

i'd rather they fixed the issues and left floats enabled, although they're not much use without the Math library.

I'd rather have floats enabled by default and modify the example code accordingly.
