% In shader model 2.0, native compares two numbers for equality checking if (a - b)*(a - b) is
|
|
% positive instead of |a - b|. We check if this causes some changes in behavior for very small and
|
|
% very large numbers.
|
|
% For large numbers the behavior is the same, even though the multiplication reaches inf, but for
|
|
% very small ones it is not because the multiplication results in 0.
|
|
%
|
|
% NOTE: Seems that subnormal numbers are considered equal to zero, at least in the WARP driver.
|
|
% Probably this is implementation dependent and deserves separate testing, so only normal numbers
|
|
% are passed on these tests.
