 Setting data
Setting data
64-bit floating-point real number data for converting to BIN value, or the first num-
S
ber of the device where floating-point real number data is stored.
D The first number of the device to store the converted BIN value.
 Functions
INTD
 Converts the 64-bit floating-point real number designated by (S) to BIN 16-bit data, and stores the result at the device num-
ber designated by (D).
S+3 S+2 S+1 S
64-bit floating-point real
number
 64-bit floating-point real numbers between -32768 to 32767 can be designated by (S+3), (S+2), (S+1), and (S).
 Stores integer values stored at (D) as BIN 16-bit values.
 After conversion, the first digit after the decimal point of the 64-bit floating-point real number is rounded off.
 When setting input values from programming tools, rounding errors may occur.
For precautions when setting input values from programming tools, refer to "6.3.4 Single/Double-Precision Real Number
Data".
