Missing log10 from codea 3.6

General
1

In the documentation Lua — Codea
There is a log10 function, but it’s not implemented.

That probably happened here. It used to work in a previous version of Codea.

Lua 5.4 deprecated some functions including pow and atan2.

I don’t think I ever used it for anything. I’m sure there’s a replacement, but at the moment I don’t know what it is.

PS. Here’s a replacement for log10.

function setup()
value=25
print(math.log(value)/math.log(10))
end

I found that since lua 5.2, the math.log() function accept the base as second parameter. So math.log(xxx,10) did the trick.

Thanks, that’s good to know. @sim The doc needs to be changed to remove the log10 and update log to show a base as the second parameter.
