-I want to buy nodemcu board and apply the Pythagora's Theorem but I dont know if sqr function exists on nodemcu lua interpreter ?
I googled on web and I found few doc with sqr() but on official Faq math funtions are omitted:
-The debug and math libraries have also been omitted to reduce the runtime footprint.- (https://nodemcu.readthedocs.io/en/dev/en/lua-developer-faq/.)
Does it exist? Thanks so much
