Description

Computes xarg to the power of kpow (or ipow) and scales the result by inorm.

Syntax

ares pow aarg, kpow [, inorm]

ires pow iarg, ipow [, inorm]

kres pow karg, kpow [, inorm]

Initialization

inorm (optional, default=1) -- The number to divide the result (default to 1). This is especially useful if you are doing powers of a- or k- signals where samples out of range are extremely common!

Performance

aarg, iarg, karg -- the base.

ipow, kpow -- the exponent.

	Note
	Use ^ with caution in arithmetical statements, as the precedence may not be correct. New in Csound version 3.493.

Examples

Here is an example of the pow opcode. It uses the file pow.csd.

<CsoundSynthesizer>
<CsOptions>
; Select audio/midi flags here according to platform
; Audio out   Audio in
-odac           -iadc    ;;;RT audio I/O
; For Non-realtime ouput leave only the line below:
; -o pow.wav -W ;;; for file output any platform
</CsOptions>
<CsInstruments>

; Initialize the global variables.
sr = 44100
kr = 4410
ksmps = 10
nchnls = 1

; Instrument #1.
instr 1
  ; This could also be expressed as: i1 = 2 ^ 12
  i1 pow 2, 12

  print i1
endin


</CsInstruments>
<CsScore>

; Play Instrument #1 for one second.
i 1 0 1
e


</CsScore>
</CsoundSynthesizer>

Its output should include a line like this:

instr 1:  i1 = 4096.000
