# sqrt

sqrt -- Returns a square root value.

## Description

Returns the square root of x (x non-negative).

The argument value is restricted for log, log10, and sqrt.

## Syntax

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

Example 1. Example of the sqrt opcode.

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

    ; Instrument #1.
    instr 1
      i1 = sqrt(64)
      print i1
    endin
    /* sqrt.orc */

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

Its output should include lines like this:

    instr 1:  i1 = 8.000
