Subject: [Caml-list] Big_int
Date: Thu, 1 Nov 2001 11:21:50 +0000 (UTC)	[thread overview]
Message-ID: <slrn9u2c2e.p4t.qrczak@qrnik.zagroda> (raw)

Why do these functions perform copies of the abs_value instead of
sharing it? I thought that big_ints are immutable.

(* Opposite of a big_int *)
let minus_big_int bi =
 { sign = - bi.sign;
   abs_value = copy_nat (bi.abs_value) 0 (num_digits_big_int bi)}

(* Absolute value of a big_int *)
let abs_big_int bi =
    { sign = if bi.sign = 0 then 0 else 1;
      abs_value = copy_nat (bi.abs_value) 0 (num_digits_big_int bi)}
