Chapter 3 Creating and Editing Screens
 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.
Example
Perform the function of COT30
o and store the result in $0 (this is a floating point
operation of signed 32-bit data).
Perform the cotangent function of $2 and store the result in $4 (this is a floating
point operation of signed 32-bit data).
 SEC (Secant Function)
Equation
Var1 = SEC (Var2)
Explanation
Perform the secant 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.
