2.7.4 SF Single-precision floating point real number constant
■
Format for single-precision floating point
● Following IEEE754 format, the double precision floating point format consists of 1 sign bit, 8
exponential bits, and 23 mantissa bits.
● Operation instructions for processing real numbers and conversion instructions for real
number integers are provided by default, so it is not necessary to worry about data format
while programming.

Storage area for single-precision floating point real number constants
● For the storage area for data of real numbers converted using the operation instructions for
single-precision floating point real number constants, 1 unit of data uses an area of 2 words
(32 bits).
● When using the storage area for real number data in data transfer instructions or other
instructions, input SF for the operation unit.
