Description

Returns the largest integer not greater than x

Syntax

floor(x) (init-, control-, or audio-rate arg allowed)

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 floor opcode. It uses the file floor.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 floor.wav -W ;;; for file output any platform
</CsOptions>
<CsInstruments>

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

instr 1

idiv init 1

loop:
inumber = 9
i1  = inumber / idiv
ifl = floor(i1)
print inumber, idiv, ifl ;print number / idiv = result using floor
idiv = idiv + 1
if (idiv <= 10) igoto loop

endin
</CsInstruments>
<CsScore>

i 1 0 0
e

</CsScore>
</CsoundSynthesizer>

The output should include lines like these:

instr 1:  inumber = 9.000  idiv = 1.000  ifl = 9.000
instr 1:  inumber = 9.000  idiv = 2.000  ifl = 4.000
instr 1:  inumber = 9.000  idiv = 3.000  ifl = 3.000
instr 1:  inumber = 9.000  idiv = 4.000  ifl = 2.000
instr 1:  inumber = 9.000  idiv = 5.000  ifl = 1.000
instr 1:  inumber = 9.000  idiv = 6.000  ifl = 1.000
instr 1:  inumber = 9.000  idiv = 7.000  ifl = 1.000
instr 1:  inumber = 9.000  idiv = 8.000  ifl = 1.000
instr 1:  inumber = 9.000  idiv = 9.000  ifl = 1.000
instr 1:  inumber = 9.000  idiv = 10.000  ifl = 0.000
