/ — Division operator.

Arithmetic operators perform operations of change-sign (negate), don't-change-sign, logical AND logical OR, add, subtract, multiply and divide. Note that a value or an expression may fall between two of these operators, either of which could take it as its left or right argument, as in

a + b * c.

In such cases three rules apply:

1. * and */* bind to their neighbors more strongly than + and −. Thus the above expression is taken as

a + (b * c)

with * taking b and c and then + taking a and b * c.

2. *+* and *−* bind more strongly than &&, which in turn is stronger than ||:

a && b - c || d

is taken as

(a && (b - c)) || d

3. When both operators bind equally strongly, the operations are done left to right:

a - b - c

is taken as

(a - b) - c

Parentheses may be used as above to force particular groupings.

The arguments of / can be scalar values or k-rate one dimensional arrays (vectors), or any combination. If one of the arguments is an array, so is the value.

Here is an example of the / operator. It uses the file *divides.csd*.

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

Its output should include lines like these:

retrigger rate per note duration = 3.333333 retrigger rate per note duration = 5.000000 retrigger rate per note duration = 0.666667
