int8

[relez]

If i have well understood int8 stands for sbyte.
Now, this code is ok:

Code: Select all

class Program
   def main is shared
      i08 as int8
      i08 = 127

but this is ko:

Code: Select all

class Program
   def main is shared
      i08 as int8
      i08 = -1

as it sends:
00049.cobra(4): error: Incompatible types. Cannot assign value of type int on th
e right to int8 on the left.

What am i missing? I obtain the same error with int16 while it's ok with int32 and int64.

I tried it and this looks like a bug to me. The workaround is easy; cast the number to the type:

int08 = -1 to int8

Ok, created ticket #45.

This incorrect typing of numeric literals was also one of the reasons for ticket:29 (a workaround) and its subsequent (still pending) patch.

Hmmm, nothing about the description of that ticket indicates to me that it addresses the typing of small integer literals...

[hopscc]

read it again - size and sign - same as your workaround (casting).
It doesnt however address the real bug - that it shouldnt be necessary to equate the type exactly or cast to the receiving variable type.

ticket:45 is fixed in changeset:1717
