# exp

exp -- Returns e raised to the x-th power.

## Description

Returns e raised to the xth power.

## Syntax

exp(x) (no rate restriction)

where the argument within the parentheses may be an expression. Value converters perform arithmetic translation from units of one kind to units of another. The result can then be a term in a further expression.

## Examples

Here is an example of the exp opcode. It uses the files exp.orc and exp.sco.

Example 1. Example of the exp opcode.

    /* exp.orc */
    ; Initialize the global variables.
    sr = 44100
    kr = 4410
    ksmps = 10
    nchnls = 1

    ; Instrument #1.
    instr 1
      i1 = exp(8)
      print i1
    endin
    /* exp.orc */

    /* exp.sco */
    ; Play Instrument #1 for one second.
    i 1 0 1
    e
    /* exp.sco */

Its output should include a line like this:

    instr 1:  i1 = 2980.958
