            Bug ID: 110209
           Summary: problem with strtod strtof strtold
           Product: gcc
           Version: 4.8.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: irip at qq dot com
  Target Milestone: ---

When using strtod, strtof, and strtold functions in code to convert values that
exceed the representation range,

The error number after execution is incorrect, and the error message is:

Got 37 Expected 38 Errno return.


Requirements for this Class function in Standard C: if the correct value
exceeds the range of representation, it is necessary to add/subtract the value
(corresponding to the sign bit) HUGE_ VAL, HUGE_ VALF or HUGE_ After VALL,
return and save the value of macro ERANGE in errno.

During testing, it was found that the errno returned was not the ERANGE value,
and the ERANGE value in the error message was not a common 34, but 38

--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Gcc does not provide these functions. They are provided by the libc that gcc
links to.

In the case of Linux, it is most likely glibc but it could be musl or uclibc .
If you are using a -elf target, then libc is most likely provided by newlib.


Also GCC 4.8.x is no longer supported upstream, you should try a much newer
GCC, like GCC 9.x or even better GCC 13.
