scala
val formatted = String.format("%08d", int2Integer(42))
printf("%08d\n", 42)
println("%08d".format(42))
erlang
Formatted = io_lib:format("~8..0B", [42]),
io:format("~8..0B~n", [42]).
csharp
string.Format("{0,8:D8}", 42);

Right Space pad a number

Given the number 1024 right pad it to 6 characters "1024  "
scala
val formatted = String.format("%-6d", int2Integer(1024))
printf("%-6d\n", 1024)
println("%-6d".format(1024))
erlang
Formatted = io_lib:format("~-6B", [1024]),
io:format("~-6B~n", [1024]).
csharp
public class NumberRightPadding {
public static void Main() {
string withStringDotFormat = string.Format("{0,-6}", 1024);
string withToStringDotPadRight = 1024.ToString().PadRight(6);
}
}

Format a decimal number

Format the number 7/8 as a decimal with 2 places: 0.88
scala
val formatted = String.format("%3.2f", double2Double(7./8.))
printf("%3.2f\n", 7./8.)
erlang
Formatted = io_lib:format("~.2f", [7/8]),
io:format("~.2f~n", [7/8]).
csharp
public class FormatDecimal {
public static void Main() {
decimal result = decimal.Round( 7 / 8m, 2);
System.Console.WriteLine(result);
}
}

Left Space pad a number

Given the number 73 left pad it to 10 characters "        73"

printf("%10d\n", 73)
erlang
Formatted = io_lib:format("~10B", [73]),
io:format("~10B~n", [73]).
csharp
public class NumberLeftPadding {
public static void Main() {
string withStringDotFormat = string.Format("{0,10}", 73);
string withToStringDotPadLeft = 73.ToString().PadLeft(10);
}
}
