Chapter 3 Creating and Editing Screens

Example

Perform the function of SIN30

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

operation of signed 32-bit data).

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

operation of signed 32-bit data).

 COS (Cosine Function)

Equation

Var1 = COS (Var2)

Explanation

Perform the cosine 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.

 Var1 can be internal memory only. Var2 can be internal memory or constant.

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

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