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.

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
