floor — Returns the largest integer not greater than x
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.
Here is an example of the floor opcode. It uses the file floor.csd.

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
