actionscript 3 - Is there something like printf in Action Script 3?

Question

I searched it for while but didn't find anything like printf in Action Script.

That makes it a little difficult to generate formated strings.

Answer 1

Printf-as is a third-party library that will handle this. Here is the GitHub repo. From the README:

printf("You can also display numbers like PI: %f, and format them to a fixed precision, 
        such as PI with 3 decimal places %.3f", Math.PI, Math.PI);
// outputs: " You can also display numbers like PI: 3.141592653589793, 
// and format them to a fixed precision, such as PI with 3 decimal places 3.142"

It also plays well with dates:

var date : Date = new Date();
printf("Today is %d/%m/%Y", date, date, date);
