When you program these functions, place the value that the function is to
be performed on in brackets, for example, SIN [10]. The exception to this
is the a rc tangent function. The format for ATAN requires the division of
two values. For example, ATAN [10]/[2] is used to calculate the arc
tangent of 5.
The functions in Table 2.C are executed from left to right in a program
block. These functions are executed before the control executes any
mathematical operators like addition or subtraction. This order of
execution can only be changed by enclosing operations in brackets [ ].
Operations enclosed in brackets are executed first.
