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 file sqrt.csd.

<CsoundSynthesizer>
<CsOptions>
; 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:
; -o sqrt.wav -W ;;; for file output any platform
</CsOptions>
<CsInstruments>

sr = 44100 
ksmps = 32 
0dbfs  = 1 
nchnls = 2

instr 1

asig   pluck 0.7, 55, 55, 0, 1
kpan   line 0,p3,1 
kleft  = sqrt(1-kpan) 
kright = sqrt(kpan) 
printks "square root of left channel = %f\\n", 1, kleft	;show coarse of sqaure root values
       outs asig*kleft, asig*kright					;where 0.707126 is between 2 speakers

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
