            Bug ID: 16770
           Summary: scalb spurious "invalid" exceptions
           Product: glibc
           Version: 2.19
            Status: NEW
          Severity: normal
          Priority: P2
         Component: math
          Assignee: unassigned at sourceware dot org
          Reporter: jsm28 at gcc dot gnu.org

When the second argument to scalb (or scalbf or scalbl) is an integer too large
for conversion to int, the implementation raises a spurious "invalid" exception
when converting to int to see if the argument is not an integer.  For example,
on x86_64, scalb (1.0, 0x1p100) raises that exception (in addition to the
correct "overflow" and "inexact" exceptions).
