2   Pass
x = pi; n=5; y_correct = 3.14159; assert(isequal(myround(x,n),y_correct))

b = 3.1416e+05 c = 314159 y = 3.1416

3   Pass
x = 0.5*sqrt(2); n=6; y_correct = 0.707107; assert(isequal(myround(x,n),y_correct))

b = 7.0711e+05 c = 707107 y = 0.7071

4   Pass
x = exp(1); n=9; y_correct = 2.718281828; assert(isequal(myround(x,n),y_correct))
