When I start messing about with a new language I have a few corner cases I try out just to see what answers I expect.
For Squeak this has been OK except for cos.
The two numbers I check are totally away from those I routinely use but are stress tests.
(10**22) sin. -0.8522008497671888 "which is correct"
(10**22) cos. -0.8522008497671888 "gives the same as sin which is suspicious"
(2**120) sin. 0.377820109360752 "Also correct"
(2**120) cos. 0.377820109360752 "Also the same as the sin case. I expect -0.9258790228548379"
