Description

• 

In the Standard Units environment, the arguments for the exponential functions can be unit-free, or multiplied by a unit with the dimension logarithmic_gain. An error is returned if the dimension of the argument is not one of logarithmic gain.

• 

By default, the units of the object returned are a ratio of wave numbers (inverse length). Using energy conversions, this ratio is proportional to a voltage ratio and its square is proportional to a power ratio.

• 

Note that the first calling sequence must be entered in 2-D math notation by using either the palettes or command completion. The exponential ex will not be recognized if it is entered manually.

• 

For other properties, see the global function exp.

Examples

Notes: 

– 

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.
