Chapter 3 Creating and Editing Screens

 The display format of the variables must be floating point.

 The input variable must be a signed decimal value without the decimal point.

Example

Perform the function of TAN30

and store the result in $0 (this is a floating point

operation of signed 32-bit data).

Perform the tangent function of $2 and store the result in $4 (this is a floating point

operation of signed 32-bit data).

 COT (Cotangent Function)

Equation

Var1 = COT (Var2)

Explanation

Perform the cotangent function of the value within Var2, and store the result in Var1.

Remark

 The definition of Var2 is an angle, not radius.

 This is the operation of signed 32-bit data.

 The calculation result can be stored as signed DWORD. When the data exceeds

the length of designated unit, the data out of range will be discarded.
