## 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)

    sqrt(k/i[]) (k- or i-arrays )

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 file sqrt.csd.

Example 991. Example of the sqrt opcode.

See the sections Real-time Audio and Command Line Flags for more information on using command line flags.

    ; Select audio/midi flags here according to platform
    -odac      ;;;realtime audio out
    ;-iadc    ;;;uncomment -iadc if realtime audio input is needed too
    ; For Non-realtime ouput leave only the line below:

    kright = sqrt(kpan)

Its output should include lines like these:

    square root of left channel = 1.000000
    square root of left channel = 0.948688
    square root of left channel = 0.894437
    square root of left channel = 0.836676
    square root of left channel = 0.774620
    square root of left channel = 0.707139
    square root of left channel = 0.632499
    square root of left channel = 0.547781
    square root of left channel = 0.447295
    square root of left channel = 0.316242
