Name: exp1

Type: function

Syntax: the exp1 of <number>

Syntax: exp1(<number>)

Summary:

<return|Returns> the natural exponential of a number, minus 1.

Introduced: 1.0

OS: mac, windows, linux, ios, android

Platforms: desktop, server, mobile

Example:

exp1(myValue)

Parameters:

number:

A real number, or an expression that evaluates to a number.

Returns:

The <exp1> function <return|returns> a positive number.

Description:

Use the <exp1> function to obtain a power of e minus 1, e^ <number> - 1.

This is the inverse function of ln1, that is exp1(ln1(x)) = x and

ln1(exp1(x)) = x for any number x.

The transcendental number e appears in many mathematical formulas.

If a math operation on finite inputs produces a non-finite output, an

execution error is thrown. See <math operation|math operations> for more

information.
