Appendix 6. Calculation Range 1. Arithmetic calculation The results for dividend, multiplicand and operand are: -1 × 10100 < x ≤ -1 × 10-99, 1 × 10-99 < x ≤ 1 × 10100 or x = 0 (valid within the range of display capability) Note: Calculation results and input values less than 1 × 10-99 are considered equal to 0. 2. Function calculation Calculation accuracy In principle, calculation errors are ±1 of the last digit. (In case of exponential display, the calculation errors are ±1 of the last digit of the mantissa display.) However, a calculation error increases in continuous calculations due to accumulation of each calculation error. (This is the same for ab, a b , n!, ex, In, etc. where continuous calculations are performed internally.) Additionally, a calculation error will accumulate and become larger in the vicinity of inflection points and singular points of functions. (for example, calculating sinh X or tanh X at X = 0) Function Calculation range sin x cos x DEG : |x| < 1 × 1010 RAD : |x| < π 180 × 1010 GRAD : |x| < 10 9 × 1010 However, the following are excluded for tan x tan x DEG RAD GRAD : |x| = 90 (2n - 1) : |x| = π 2 (2n - 1) : |x| = 100 (2n - 1) sin-1 x cos-1 x -1 ≤ x ≤ 1 tan-1 x |x| < 1 × 10100 sinh x cosh x -230.2585093 ≤ x ≤ 230.2585092 tanh x sinh-1 x cosh-1 x tanh-1 x |x| < 1 × 1050 1 ≤ x ≤ 1 × 1050 |x| < 1 Notes "n" is an integer 241
