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)
ceil(k/i[]) (k- or i-arrays )

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.

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
