[Operation]
: 32-bit floating decimal point data to be converted to BIN value or head number of the devices where the floating decimal point data is stored (real number)
:
Head number of the devices where the converted BIN value will be stored (BIN 16/32 bits)
*1: Available only in multiple Universal model QCPU and LCPU
Function
INT
(1) Converts the 32-bit floating decimal point real number designated at into BIN 16-bit data and stores it at the device
number designated at .
(2) The range of 32-bit floating decimal point type real numbers that can be designated at +1 or is from -32768 to
32767.
(3) Stores integer values stored at as BIN 16-bit values.
(4) After conversion, the first digit after the decimal point of the real number is rounded off.
