From baf990e65c62f42e45fe25ac385db9536d3f1788 Mon Sep 17 00:00:00 2001
From: Bruce Hill <bruce@bruce-hill.com>
Date: Sun, 27 Apr 2025 16:49:38 -0400
Subject: Update stdlib to use `print` instead of `printf` in all cases. This
 means bringing in fpconv to do float-to-string conversion and a few updates
 to integer and number methods for string formatting.
