Case Analysis, cont.

• Example 1

  /* Let x be the absolute value of y. */

if ( y < 0 )

/* Let x be -y. */

. . .

else

/* Let x be y. */

. . .

• Example 2

  /* Let x be the absolute value of y. */

x = Math.abs(y);

I.e., sometimes case analysis is counter-productive and there is a uniform way to solve the problem.
