Parameters

Name

Description

sink

An OutputRange for accepting possibly piecewise segments of the formatted string.

formatString

A format string specifying the output format.

Available output formats:
"d"	Decimal
"o"	Octal
"x"	Hexadecimal, lower case
"X"	Hexadecimal, upper case
"s"	Default formatting (same as "d")
null	Default formatting (same as "d")

Example

toString is rarely directly invoked; the usual way of using it is via std.format.format:

import std.format : format;

auto x = BigInt("1_000_000");
x *= 12345;

writeln(format("%d", x)); // "12345000000"
writeln(format("%x", x)); // "2_dfd1c040"
writeln(format("%X", x)); // "2_DFD1C040"
writeln(format("%o", x)); // "133764340100"
