 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).
