jicman: > Where can I download your dlibs1 library? This is D1 code, it's slow because I usually print only few numbers like this:
string thousands(TyIntegral)(TyIntegral n, string separator="_") { static assert (IsType!(TyIntegral, byte, ubyte, short, ushort, int, uint, long, ulong), "thousands() accepts only a integral numeric argument."); string ns = toString(abs(n)).reverse; string[] parts; for (int i = 0; i < ns.length; i += 3) parts ~= ns[i .. (i+3) < length ? (i+3) : length]; return (n < 0 ? "-" : "") ~ parts.join(separator).reverse; } Bye, bearophile
