Hello again,
I worked on it ( challenge accepted ! )
I took a look of your implementation, I'm not sure it is necessary to
remove trailing white spaces or inner spaces ( " 1 000 000 " is not a
correct representation of a number, that's all ! )
Or you have to manage "\t", "," or any localized separator.
In lot of language when you convert "123toto" you get 123 not an error.
And does not allow "1.123" is a mistake for me since uint64(1.123) ->
1(ui64).
I made an implementation in builtin for all (u)int functions that raises
error only on too long input string ("10000000000000000000" for example
) and empty string ( but we can convert to 0 like %nan )
I manage "nan", "NaN" "%nan", "inf", "Inf", "%inf", "-inf", "-Inf",
"-%inf" to respectively 0, minval and maxval
And "icing on the cake", is little bit faster than yours :p
(between 2 and 100 times depending of input size, C++ vs script)
(missing NRT, changes ... but it is Saturday ^^ )

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:

Hello Samuel,
Currently, parser ... lexer, in fact, try to read "number" and
convert it to floating point number, at this moment, we have no idea
what the final goal of this number.
After that, the parser try to understand what to do with this number
(already a double).
So I think the first case is not possible with the current management
of numbers.
For string argument, I think it cannot be done easily in an overload
macro for the same reason.
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
