	1252	Suffixed integer constant implicitly converted to different integer type.

Arithmetic type - Balancing

In the course of a type balancing operation, a suffixed integer constant is being implicitly converted to another type. Is the type conversion really intended or does this indicate that the suffix is inappropriate ?

Note that the type of an integer constant depends on its value and the implemented size of an int (e.g. whether it is a 16 bit or 32 bit quantity ) as well as the presence of suffixes. More ...

For example:
