*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.
■Description, data type of result
Processing details
• 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.

(single precision real number)
• 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.
Operation error
An operation error will occur if:
• The (S) data is not a valid 32-bit floating-point type.
Program example
■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
