- The result of 0.0/0.0 was being rendered as a lot of
zeroes in the integer portion, as in this example:
DBGvpp# show physmem
0: 16 objects, 576k of 582k used, 3k free, 0 reclaimed, 2k overhead,
16380k capacity
alloc. from small object cache: 0 hits 0 attempts (0.00%) replacements 0
alloc. from free-list: 0 attempts, 0 hits (0.00%), 0 considered (per-attempt 0.00)
alloc. from vector-expand: 16
allocs: 16 73643.06 clocks/call
frees: 0 000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000.00 clocks/call
- Add two macros to vppinfra/math.h that use compiler builtins to check
for NaN and Infinity and then use them in format_float().
