Note
Negative values inside of calculations must be enclosed within parentheses. For details, see "Calculation Priority Sequence."
Logarithmic Functions
Example 1: log 1.23 = 0.089905111
- 123
- 0.089905111
Example 2: ln 90 (= loge 90) = 4.49980967
- 90
- 4.49980967
Example 3: ln e = 1 (fx-82MS/fx-85MS/fx-300MS/fx-350MS only)
(e)- 1.
