I'm aware of NaN payload but have not seen C code that
* has MIN/MAX macros for the min/max payload value for a give FP type
* sets a NaN value with a specific payload
* extracts a payload from a NaN
are there standard api's for this?
for the casual reader, comparisons on
Who can explain this strange behavior of typeset (-l) -En? For me it looks like
a bug.
echo 2^69 | bc

/bin/ksh -c 'typeset -l -E18 x;x=$(( pow(2,69) ));echo $x'
5.90295810358705652e+20
/bin/ksh -c 'typeset -l -E19 x;x=$(( pow(2,69) ));echo $x'

I get this:
ksh -c 'print -- $(( log2( int(pow(2,69) )) ))'
69
But it should print 'nan', as it does if I use explicitly an
intermediate integer
