V3026. The constant NN is being utilized. The resulting value could be inaccurate. Consider using the KK constant.

Dec 14 2015

The analyzer has detected an issue that deals with using constants of poor accuracy in mathematical calculations.

Consider this example:

double pi = 3.141592654;

This way of writing the pi constant is not quite correct. It's preferable to use mathematical constants from the static class Math:

double pi = Math.PI;

The analyzer doesn't output the warning for cases when constants are explicitly defined as of 'float' type. The reason is that type 'float' has fewer significant positions than type 'double'. That is why the following code won't trigger the warning:

float f = 3.14159f; //ok
