Processing details
■INTD
• Converts the 64-bit floating decimal point real number designated at (S) into BIN 16-bit data and stores it at the device
number designated at (D).
S +3 S +2 S +1 S
64-bit floating-point
real number
• The range of 64-bit floating decimal point type real numbers that can be designated at (S)+3, (S)+2, (S)+1 or (S) is from -
32768 to 32767.
• Stores integer values stored at (D) as BIN 16-bit values.
• The converted data is the value rounded 64-bit floating-point real number to the first digit after the decimal point.
• When an input value is set using a programming tool, a rounding error may occur. For precautions, refer to Page 89
Precautions.
■DINTD
• Converts 64-bit floating decimal point type real number designated by (S) to BIN 32-bit data, and stores the result at the
device number designated by (D).
S S S S
+3 +2 +1

• The range of 64-bit floating decimal point type real numbers that can be designated at (S)+3, (S)+2, (S)+1 or (S) is from -
2147483648 to 2147483647.
• The integer value stored at (D)+1 and (D) is stored as BIN 32 bits.
• The converted data is the value rounded 64-bit floating-point real number to the first digit after the decimal point.
• When an input value is set using a programming tool, a rounding error may occur. For precautions, refer to Page 89
