Function `std.bigint.BigInt.opBinaryRight`

Implements operators with built-in integers on the left-hand side and BigInt on the right-hand side.


						
				BigInt opBinaryRight(string op, T)
				(
				

				  T y
				

				) const pure nothrow @safe
				

				if ((op == "+" || op == "*" || op == "|" || op == "&" || op == "^") && isIntegral!T);
				

				

				BigInt opBinaryRight(string op, T)
				(
				

				  T y
				

				) const pure nothrow @safe
				

				if (op == "-" && isIntegral!T);
				

				

				T opBinaryRight(string op, T)
				(
				

				  T x
				

				) const pure nothrow @safe
				

				if ((op == "%" || op == "/") && isIntegral!T);

Example

auto x = BigInt("100");
BigInt y = 123 + x;
writeln(y); // BigInt("223")

BigInt z = 123 - x;
writeln(z); // BigInt("23")

// Dividing a built-in integer type by BigInt always results in
// something that fits in a built-in type, so the built-in type is
// returned, not BigInt.
assert(is(typeof(1000 / x) == int));
writeln(1000 / x); // 10
