FNC111 – EZCP / Floating Point Zone Compare
Outline
This instruction compares data (binary floating point) with two values (one zone), and outputs the comparison result to
three consecutive bit devices.
→
For handling of floating point, refer to Subsection 5.1.3.
1. Instruction format
2. Set data
*1.
When a constant (K or H) is specified, it is automatically converted from binary into binary floating point (real
number) when the instruction is executed.
3. Applicable devices
S
: "D
.b" cannot be indexed with index registers (V and Z).
