For the logarithmic function “log(”, you can specify base m using the syntax “log (m, n)”.
If you input only a single value, a base of 10 is used for the calculation.

“ln(” is a natural logarithm function with base e.

You can also use the key when inputting an expression with the form of “logmn” while using MathI/MathO or MathI/DecimalO format. For details, see Example 1. Note that you must input the base (base m) when using the key for input.

Example 1: log216 = 4

• A base of 10 (common logarithm) is used if no base is specified.

Example 3: ln 90 (= loge 90) = 4.49980967, ln e = 1
