# abs

abs -- Returns an absolute value.

## Description

Returns the absolute value of x.

## Syntax

abs(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 abs opcode. It uses the files abs.orc and abs.sco.

Example 1. Example of the abs opcode.

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

    ; Instrument #1.
    instr 1
      i1 = -6
      i2 = abs(i1)

      print i2
    endin
    /* abs.orc */

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

Its output should include lines like:

    instr 1:  i2 = 6.000
