Bug ID: 18217
Summary: erfcf spurious underflows
Product: glibc
Version: 2.21
Status: NEW
Severity: normal
Priority: P2
Component: math
Assignee: unassigned at sourceware dot org
Reporter: jsm28 at gcc dot gnu.org
The flt-32 implementation of erfcf produces spurious underflow exceptions. For
example, on x86_64, erfcf (0x1p-55f) produces an underflow exception (while the
return value is correctly very close to 1).
