FCMP (Floating Point Value Comparison)
Equation
Var1 = FCMP (Var2, Var3)
Explanation
Compare the floating point value in Var2 and Var3 and store the result in Var1.
The comparison methods include:
Var1=0, Var2 = Var3
Var1=1, Var2 > Var3
Var1=2, Var2 < Var3
Remark
The calculation result can be stored as signed DWORD.
Var1 can be internal memory only. Var2 and Var3 can be internal memory or
constant.
Example
Compare the floating point value in $0 and $2 and store the result in $4 (this is an
operation of signed 32-bit data).
