            Bug ID: 18583
           Summary: fmodl, remainderl spurious inexact for NaN results
           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
  Target Milestone: ---

Similar to bug 18245 for sqrtl, and with the same underlying cause, fmodl
(-1.1L, 0.0L) and similar cases with (Inf, y) and with remainderl, produce
spurious "inexact" exceptions with NaN results (these being fully determined
functions, they should not do so, whereas for most functions such exceptions
are OK).
