Logarithmic and Exponential Functions
• Be sure to specify Comp for Mode in the Setup screen.
Example
log 1.23 (log 1.23) = 0.08990511144

• The Linear input/output mode and Math input/output mode produce different results when
two or more powers are input in series, like: 2
Linear input/output mode: 2^3^2 = 64
This is because the Math input/output mode internally treats the above input as: 2^(3^(2)).
Hyperbolic and Inverse Hyperbolic Functions
• Be sure to specify Comp for Mode in the Setup screen.
Example
sinh 3.6 = 18.28545536
