# Idiom #23 Convert real number to string with 2 decimal places

Given a real number x, create its string representation s with 2 decimal digits following the dot.

``s = f'{x:.2f}'``
``s =  '{:.2f}'.format(x)``
``#include <stdio.h>``
``sprintf(s, "%.2f", x);``
``````#include <iomanip>
#include <sstream>``````
``````std::stringstream ss;
ss << std::fixed << std::setprecision(2) << x;
s = ss.str();``````
``string s = \$"{x:F2}";``
``import std.string;``
``string str = format("%.2s", x);``
``var s = x.toStringAsFixed(2);``
``s = Float.to_string(x, decimals: 2)``
``S = io_lib:format("~.2f", [X]).``
``  write (unit=s,fmt="(F20.2)") x``
``import "fmt"``
``s := fmt.Sprintf("%.2f", x)``
``````s <- showFFloat (Just 2) x ""
``````
``num.toFixed(2)``
``String s = String.format("%.2f", x);``
``s = "%.2f".format(x)``
``s = string.format("%.2f",x)``
``\$s = sprintf('%.2f', \$x);``
``uses SysUtils;``
``s := format('%.2f',[ x]);``
``\$s = sprintf "%.2f", \$x;``
``s = "%.2f" % x``
``let s = format!("{:.2}", x);``
