From 6567ba0c60d6e1366f7ac6e77665730e657e8eca Mon Sep 17 00:00:00 2001 From: Richard Henderson Date: Mon, 15 Mar 2021 12:51:17 -0600 Subject: utils: Use fixed-point arithmetic in qemu_strtosz Once we've parsed the fractional value, extract it into an integral 64-bit fraction. Perform the scaling with integer arithmetic, and simplify the overflow detection.
