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

Name	Description
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
