V605. Unsigned value is compared to the NN number. Consider inspecting the expression.

Feb 27 2012

The analyzer has detected a potential error in an expression where an unsigned variable is compared to a negative number. This is a rather rare situation and such a comparison is not always an error. However, getting the V605 warning is a good reason to review the code.

unsigned u = ...;
if (u < -1)
{ ... }

This diagnostic is classified as:
