This small program read lines from input.txt in a loop, and print the line and
the atof value of the line out. But the first atof returns a 0 instead of the
expected 123.45.

[Bug c++/116527] New: conversion from float to char incorrect
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=116527 Bug ID: 116527 Summary: conversion from float to char incorrect Product: gcc Version: 14.1.1 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ Assignee: unassigned at gcc dot gnu.org Reporter: xiaoyi_wu at yahoo dot com Target Milestone: --- Created attachment 59024 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=59024&action=edit source code to indicate the problem I have a fedora 40 virtual machine running on M3 MacBook Pro. Since the M3 is arm CPU instead of Intel, the default char in C++ in fedora is unsigned (unlike on Intel, which is signed). In the attached source code, function foo returns float, function bar returns double, both are assigned to char variable a and b. But the conversion is incorrect for float, and also for double when compiled without -O. Here is the system and gcc version: limo:work$ uname -a Linux limo 6.9.6-200.fc40.aarch64 #1 SMP PREEMPT_DYNAMIC Fri Jul 21 16:23:18 UTC 2024 aarch64 GNU/Linux limo:work$ g++ -v Using built-in specs.

If I compile without optimization: $ gcc -Wall main.cc then the output is this: -5 0 0 -4 0 0 -3 0 0 -2 0 0 -1 0 0 0 0 0 1 1 1 2 2 2 3 3 3 4 4 4 which means both negative float and negative double convert to char becomes 0. Basically, negative float convert to char will result in 0, while negative double convert to char will result in 0 when compiled without optimization.
