[Scilab-Dev] Big literal integers for int64() and uint64()

[Samuel Gougeon]

Hello Antoine,

Thanks for your answer.
I have opened a bug report #15837 
<http://bugzilla.scilab.org/show_bug.cgi?id=15837> about this topic.

About the overload:

In the report, i have posted a proposal for a working 11-rows-long 
%c_uint64() overload (without the error messages ;)
With it, we get for instance

--> %c_uint64("9000000000000001000") + [ 1 -1001 ; 4 7]
  ans  =
   9000000000000001001  8999999999999999999
   9000000000000001004  9000000000000001007

whereas
--> uint64(9000000000000001000) + [ 1 -1001 ; 4 7]
  ans  =
   9000000000000001025  9000000000000000023
   9000000000000001028  9000000000000001031

It can process any relevant input array of any number of dimensions.

Best regards
Samuel
