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
