Actually a large number of operations take place internally at 15 digits - especially matrix, trigonometric and exponential operations.

Also, on some operations the final resulting answer is determined by the current display setting. I think integration is the only one like this, but I could be wrong. If you set display to FIX 3, your integer is within 1 digit of the third decimal place. Set it to 9 and the answer will take longer to compute.
