Subject: [musl] Bug report: fcvt seems dysfunctional
Date: Tue, 6 Sep 2022 11:27:15 +0200 [thread overview]
Message-ID: <7bf9a30d-4ba8-1fe7-8c80-db99446db307@gmail.com> (raw)
Executing something like `fcvt(0.01, 1, &decpt, &sign)` under musl
results in a return value of "00", decpt == 1 and sign == 0.
glibc instead returns an empty string, decpt == -1 and sign == 0.
I believe glibc's behavior is the correct one as mandated by POSIX.2004
because it specifies that the high-order digit shall be non-zero unless
the value is 0, which is not the case here, meaning that musl cannot
return a string containing '0' as the first character.
