• Trigonometric functions
• Logarithmic/Expontial functions
• Convert to Degrees
• Convert to Radians
Converting Data for the Math and Numerical Functions
The program may need to include logic to convert data to a different type before using a
Math or Numerical function. The description of each function includes information about
appropriate data types. The section Data Type Conversion Functions explains how to
convert data to a different type.
10.5.1 Math and Numerical Functions Add, Subtract,
Multiply, Divide
The standard math functions are Addition, Subtraction, Multiplication, and Division. The
Division function rounds down; it does not round to the closest integer. (For example, 24
DIV 5 = 4.)
When a math function receives power flow, the operation is performed on input
parameters I1 and I2. Parameters I1, I2, and output Q must be the same data type.

INT
Input 1 I1 Q
Input 2 I2
The math functions pass power if there is no math overflow. If an overflow occurs, the
result is the largest value with the proper sign and no power flow.
