Test Suite flawed: should account for inherent imprecision of floating-point numbers.

Test	Status	Code Input and Output
1	Pass	d = 20; y_correct = 20+(10*pi); assert(isequal(perm_semicircle(d),y_correct)) y = 51.4159
2	Fail	d = 100; y_correct = 100+(50*pi); assert(isequal(perm_semicircle(d),y_correct)) y = 257.0796 Assertion failed.

Pass

d = 20; y_correct = 20+(10*pi); assert(isequal(perm_semicircle(d),y_correct))

y = 51.4159

Fail

d = 100; y_correct = 100+(50*pi); assert(isequal(perm_semicircle(d),y_correct))

y = 257.0796

Assertion failed.
