Results of Calculations

Sometimes you may see a statement like this:
A = A * A * (Cos (A) + Sin (A) )
The program takes the quantity represented by A and performs all of the followi
value:
•
Multiply A by itself.
•
Calculate the cosine of A.
•
Calculate the sine of A.
•
Add the cosine and the sine together.
•
Multiply that result by the square of A.
At this point, the quantity represented by A has not be
value placed in the memory location labeled
Note that you can write more than one statement on a line, separated by colons, like this
A = B * Cos (34 * Theta) * Sin (55 * Theta) : B = A * A + Z * Z

Order of Calculations

Operations are perform ed in the following order:
•
Contents of brac kets
•
Exponentiation
•
Division and mul tiplicatio
•
Addition and sub traction

Here are some examples of the uses of brackets:
Brackets are worked out before any other operations are performed.
Use brackets to force the result you want, and also to clarify a calculation.
