            Bug ID: 15504
           Summary: nearfloat(..,int32(1)) returns nothing and generates
                    no error. Same issue with all types of encoded
                    integers inputs.
           Product: Scilab software
           Version: 6.0.1
          Hardware: (not used)
                OS: All OS
            Status: NEW
          Severity: Medium
          Priority: (field not used)
         Component: Numerical Math
          Assignee: bugzilla.admin at scilab.org

BUG DESCRIPTION:
----------------
In Scilab 5.5.2:
---------------
-->nearfloat("pred",int32(1))
                           !--error 201 
nearfloat: Wrong type for argument #2: Real or Complex matrix expected.

-->nearfloat("succ",int32(1))
                           !--error 201 
nearfloat: Wrong type for argument #2: Real or Complex matrix expected.

Same thing with int8, uint8, int16, uint16, uint32 inputs.

In Scilab 6.0:
-------------
--> nearfloat("pred", int32(1))  // nothing displayed
--> nearfloat("succ", int32(1))  // idem  
--> type(nearfloat("pred", int32(1)))
--> type(nearfloat("pred", int32(1)))

type: Wrong number of input arguments: 1 expected.

This makes troubles when the result is tentatively assigned, like
"Unable to extract right part expression."


ERROR LOG:
----------
none. The bug is the miss of error message

HOW TO REPRODUCE THE BUG:
-------------------------
for i = [1 2 4 8 11 12 14 18]
    nearfloat("pred", iconvert(1,i));
    nearfloat("succ", iconvert(1,i));
end
// Should yield 16 error messages, while noting is displayed

OTHER INFORMATION:
------------------
Bug found when analyzing bugs of round() with int64 and uint64
