	1250	Unsuffixed integer constant causes implicit conversion of other operand.

Arithmetic type - Balancing

An unsuffixed integer constant is one operand of a binary operator for which type balancing occurs. Message 1250 is generated to identify the fact that this unsuffixed constant causes the other (non-constant) operand to undergo an implicit type conversion and so its type is of some significance. Message 1255 is also generated because, the value of the constant is large and so,despite the absence of a suffix, it is not of type int (it may be of type unsigned int or one of the larger integer types).

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 ...
