## ceil

ceil — Returns the smallest integer not less than x

## Description

Returns the smallest integer not less than x

## Syntax

    ceil(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 ceil opcode. It uses the file ceil.csd.

Example 102. Example of the ceil opcode.

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

    sr = 44100
    ksmps = 32
    nchnls = 2

    instr 1

    inum = p4
    iceil = ceil(inum)
    print iceil

Its output should include lines like:

    instr 1:  iceil = -1.000
    instr 1:  iceil = 1.000
    instr 1:  iceil = 1.000
    instr 1:  iceil = 1.000
    instr 1:  iceil = 0.000
    instr 1:  iceil = 0.000
    instr 1:  iceil = 0.000
