(Note-1) : The data is handled as the 32-bit integer type on the program, but store the 32-bit floating-point data in the device.
[Setting data]
Setting data Description Data type of result
(S)
Data which will be converted into 64-bit
floating-point value
64-bit floating-point type
[Functions]
(1) The 32-bit floating-point (single precision real number) value stored in the device
specified with (S) is converted into the 64-bit floating-point (double precision real
number) value.
Convertible data ranges are shown below.
-3.40
10

(single precision real number)
(2) The 64-bit floating-point type is used as the data of floating-point type in the
Motion SFC program. Use this instruction to input the data of 32-bit floating-point
type from the external devices.
[Errors]
(1) An operation error will occur if:
• The (S) data is not a valid 32-bit floating-point type.
[Program examples]
(1) Program which converts the 32-bit floating-point value data of D2000L into 64-bit
floating-point value data and substitutes the result to #0F
#0F = DFLT(D2000L)
