VALUE
rb_int_to_s(int argc, VALUE *argv, VALUE x)
{
    int base;

    if (rb_check_arity(argc, 0, 1))
        base = NUM2INT(argv[0]);
    else
        base = 10;
    return rb_int2str(x, base);
}

Returns a string containing the place-value representation of self in radix base (in 2..36).

Example

12345.to_s               # => "12345"
12345.to_s(2)            # => "11000000111001"
12345.to_s(8)            # => "30071"
12345.to_s(10)           # => "12345"
12345.to_s(16)           # => "3039"
12345.to_s(36)           # => "9ix"
78546939656932.to_s(36)  # => "rubyrules"

Raises an exception if base is out of range.
