6.3 Data conversion instructions
6.3.6 INTD, INTDP, DINTD, DINTDP
DINTD
(1) Converts 64-bit floating decimal point type real number designated by to BIN 32-bit data, and stores the result at the
device number designated by .
(2) The range of 64-bit floating decimal point type real numbers that can be designated at +3, +2, +1 or is from
-2147483648 to 2147483647.
(3) The integer value stored at +1 and is stored as BIN 32 bits.
(4) The converted data is the value rounded 64-bit floating-point real number to the first digit after the decimal point.
Operation Error
(1) In any of the following cases, an operation error occurs, the error flag (SM0) turns ON, and an error code is stored into
SD0.
Program Example
(1) The following program converts the 64-bit floating decimal point type real number at D20 to D23 with BIN 16-bit data, and
stores the result at D0.
