Operands:
S : Source address D : Destination address to store the result
Description:
1. The binary floating point value of register S is converted to BIN integer and stored in register
D .
2. This instruction is the opposite of the API 49 (FLT) instruction.
3. Flags: M1020 (Zero flag), M1021 (Borrow flag), M1022 (Carry flag)
If the absolute value of the result is larger than the maximum allowable floating point value, the
carry flag M1022= ON.
If the absolute value of the result is less than the minimum allowable floating point value, the
borrow flag M1021= ON.
If the result exceeds the integer or double integer range (an overflow occurs), the Carry flag
M1022= ON.
Program Example:
1. When X0= ON, the binary floating point value of (D1, D0) will be converted to BIN integer and
the result is stored in (D10).
2. When X1= ON, the binary floating point value of (D21, D20) will be converted to BIN integer
and the result is stored in (D31, D30).
