Above link to Sun Forums became dead after migration to Oracle.

If memory serves, back then I suggested to consider MicroFloat library .

There is also a chance that mentioned Sun forums thread was migrated to this one: Sin & Cos with CLDC . Since message formatting was broken in migration and since no one knows if migrated thread will stay where it is now, here's the "snapshot" of what is there:

• CLDC 1.0 (JSR 30) doesn't have float / double and trigonometric functions
  For devices limited to CLDC 1.0, search Google for 'CLDC Math library' - there's plenty info

• CLDC 1.1 (JSR 139) has some trigonometric and double / float functions in Math package
  of functions mentioned in question, sin cos tan are there, asin acos atan atan2 aren't
