Parameters

maxDigits

Examples

Appender!(char[]) sink;
int num = 12345;
num.toAlphaInto(sink);
assert(sink.data == "12345");
assert(sink.data == num.to!string);
import std.array : Appender;

Appender!(char[]) sink;

{
    enum num = 123_456;
    num.toAlphaInto(sink);
    assert((sink.data == "123456"), sink.data);
    sink.clear();
}
{
    enum num = 0;
    num.toAlphaInto(sink);
    assert((sink.data == "0"), sink.data);
    sink.clear();
}
{
    enum num = 999;
    num.toAlphaInto(sink);
    assert((sink.data == "999"), sink.data);
    sink.clear();
}
{
    enum num = -987;
    num.toAlphaInto(sink);
    assert((sink.data == "-987"), sink.data);
