Bug ID: 26446
Summary: std::numeric_limits<long double>::max_digits10
massively wrong for ppc
Product: libc++
Version: unspecified
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: All Bugs
Assignee: unassignedclangb...@nondot.org
Reporter: richard-l...@metafoo.co.uk
CC: llvm-bugs@lists.llvm.org, mclow.li...@gmail.com
Classification: Unclassified
libc++ thinks that std::numeric_limits<long double>::max_digits10 is 33 for
ppc64-linux. However, both DBL_MAX + DBL_DENORM_MIN and DBL_MAX +
DBL_DENORM_MIN*2 can be exactly represented by a PPC double double, and you
need around 633 decimal digits to distinguish those two values.
