Operands:
S
: Source device
D
: Converted result
Explanations:
1.
S
occupies 2 consecutive devices. See the specifications of each model for their range of use.
2. Flags: M1020 (zero flag); M1021 (borrow flag); M1022 (carry flag)
3. The binary floating point value of the register designated by
S
is converted to BIN integer and stored in the
register designated by
D
. The decimal of BIN integer is left out.
4. This instruction is the inverse operation of API 49 FLT instruction.
5. If the converstion result = 0, the zero flag M1020 = On
If there is any decimal left out, the borrow flag M1021 = On.
If the result exceeds the range listed below, the carry flag M1022 = On.
16-bit instruction: -32,768 ~ 32,767
32-bit instruction: -2,147,483,648 ~ 2,147,483,647
Program Example:
1. When X0 = On, the binary floating point (D1, D0) will be converted into BIN integer and the result will be stored
in (D10). The decimal of BIN integer will be left out.
2. When X1 = On, the binary floating point (D21, D20) will be converted into BIN integer and the result will be
stored in (D31, D30). The decimal of BIN integer will be left out.
