Wrong float generator in regression test vecaddx

In the test app regression/vecaddx, the Comparator<float>::generate return type is expected to be float, but it is int.

vortex/tests/regression/vecaddx/main.cpp

Lines 53 to 55 in f0e6a43

    
           static int generate() {  
        
             return static_cast<float>(rand()) / RAND_MAX; 
        
           }

This method is used to generate random float vectors, but it always yields 0 under the mistake above which makes the test not rigorous enough (always testing 0.0 + 0.0 = 0.0).

	static int generate() {
	return static_cast<float>(rand()) / RAND_MAX;
	}
