frac

frac — Returns the fractional part of a decimal number.

Description

Returns the fractional part of x.

Syntax

frac(x) (init-rate or control-rate args; also works at audio rate in Csound5)

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 frac opcode. It uses the files frac.orc and frac.sco.

Example 162. Example of the frac opcode.

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

; Instrument #1.
instr 1
  i1 = 16 / 5
  i2 = frac(i1)

  print i2
endin
/* frac.orc */

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

        

Its output should include a line like this:

instr 1:  i2 = 0.200
