Chapter 3 Creating and Editing Screens
Add up the values contained within the internal memory address $6, $8 and $10, and
the grand total is stored in the address $12 (this is an operation of unsigned 32-bit
data).
FADD (Floating Addition)
Equation
Var1 = FADD (Var2, Var3)
Explanation
Perform the addition on Var2 and Var3, and store the addition result in Var1.
Remark
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 and Var3 can be internal memory or
constant.
Example
Add a value of 1.0 to $0 and store the value in $0 (this is a floating point operation of
signed 32-bit data).
