natural logarithmic function in the Standard Units environment
general logarithmic function in the Standard Units environment
common logarithmic function in the Standard Units environment
algebraic expression, the base of the logarithm
In the Standard Units environment, the arguments for the logarithmic functions can be unit-free, or multiplied by a unit that is energy-equivalent to a rational power of the dimension length(base)/length. Examples of such units are watt/watt(base) (power ratio) or voltage/voltage(base) (voltage ratio).
For non-unit-free expressions, the result is expressed in the dimension of logarithmic gain. The unit of the object returned is the neper by default.
For other properties, see the global function ln.
To enter a unit in 2-D Math input, select the unit from the appropriate Units palette. If the unit you want is not there, select unit and then enter the unit.
When you edit a unit, double brackets appear around it.
