I am making some animations with the `@animate` macro and would like to display time in the title.

Right now I am using `string(round(t,digits=2))` but whenever the converted number has less than two decimals the text gets re-aligned resulting in a jittering effect.

![animation](https://global.discourse-cdn.com/julialang/original/3X/9/a/9a6de2a5cb0e226b8f09234b033e75baa0e1a02c.gif)

The command `@printf("%.2",1)` produces the desired output but sends it to the IO instead of a variable.

sprintf should do what you want.

See [`@sprintf`](https://docs.julialang.org/en/v1/stdlib/Printf/#Printf.@sprintf).

Does indeed. Thank you very much.
