For example, 2 " t calculates the cube of 2. 2 Results The calculator can display up to 10 digits plus a minus sign (-9, 999, 999, 999 through 9, 999, 999, 999) and a 2-digit exponent. Results with more than 10 digits display in scientific notation. Basic Arithmetic D>82 J O 67 . Pi is calculated with 12 digits (3. 14159265359), displayed with 10 digits (3. 141592654).
