Hot to convert float to string in lua?

I’m trying to make a score change in the score text but I need to turn the float variable into a string. I’m not sure how to do this in lua or lumberyard. Thank you for your help.

From the Lua Programming Guide at the bottom, use tostring():

print(tostring(10) == "10") --> true
print(10 .. "" == "10") --> true

Thank you Roosevelt
