string.format(formatstring, e1, e2, ...)
Create a formatted string from the format and arguments provided. This is similar to the printf("format",...) function in C. An additional option %q puts quotes around a string.
- c, d, E, e, f, g, G, i, o, u, X, and x all expect a number as argument.
- q and s expect a string.
> = string.format("%s %q", "Hello", "Lua user!") -- string and quoted string
Hello "Lua user!"
> = string.format("%c%c%c", 76,117,97) -- char
Lua
> = string.format("%e, %E", math.pi,math.pi) -- exponent
