conversion of octave_int<short int> to int?

[Eric Chassande-Mottin]

hi,

----------------------------------------------------------------------------------------------------
int16NDArray arcs=myArcs(startNode).int16_array_value();

[...]

int arcIndex = (int) arcs(k) - 1;
[...]
----------------------------------------------------------------------------------------------------

with the above code, I get the following error at compilation:

csp.cc:83: note: candidate 2: operator-(float, int) <built-in>
csp.cc:83: error: conversion from 'octave_int<short int>' to 'int' is ambiguous
/usr/include/octave-2.9.14/octave/oct-inttypes.h:260: note: candidates
are: octave_int<T>::operator float() const [with T = short int]
/usr/include/octave-2.9.14/octave/oct-inttypes.h:258: note:
     octave_int<T>::operator double() const [with T = short int]
/usr/include/octave-2.9.14/octave/oct-inttypes.h:256: note:
     octave_int<T>::operator char() const [with T = short int]
/usr/include/octave-2.9.14/octave/oct-inttypes.h:254: note:
     octave_int<T>::operator bool() const [with T = short int]


while  with the change

double arcIndex = (double) arcs(k) - 1;

the code does compile. Why is the conversion to int disabled?

thanks,
eric
