Function std.bigint.BigInt.getDigit

Gets the nth number in the underlying representation that makes up the whole BigInt.

T getDigit(T) (
  size_t n
) const
if (is(T == ulong) || is(T == uint));

Parameters

NameDescription
T the type to view the underlying representation as
n The nth number to retrieve. Must be less than ulongLength or uintLength with respect to T.

Returns

The nth ulong in the representation of this BigInt.

Example

auto a = BigInt("1000");
writeln(a.ulongLength()); // 1
writeln(a.getDigit(0)); // 1000

writeln(a.uintLength()); // 1
writeln(a.getDigit!uint(0)); // 1000

auto b = BigInt("2_000_000_000_000_000_000_000_000_000");
writeln(b.ulongLength()); // 2
writeln(b.getDigit(0)); // 4584946418820579328
writeln(b.getDigit(1)); // 108420217

writeln(b.uintLength()); // 3
writeln(b.getDigit!uint(0)); // 3489660928
writeln(b.getDigit!uint(1)); // 1067516025
writeln(b.getDigit!uint(2)); // 108420217
