3) Applications and precautions
The following explains the applications and precautions for the cases where
internal operation processing is performed with double precision and not
performed.
• When internal operation processing is performed with double precision
This option is used when accuracy is required to ensure compatibility with
the conventional models.
When using an instruction such as SIN or COS, with which many real
number operations are performed internally, accuracy is increased by
performing internal operation processing with double precision.
• When internal operation processing is not performed with double precision
This option is used when real number operation speed must be increased.
However, since internal operation is performed with single precision (32
bits), real number operation speed increases but accuracy may decrease.
POINT
1. The monitor function for GX Developer permits monitoring the real number
data of the CPU module.However, if an attempt is made to monitor the data
that cannot be represented as a real number, e.g. "FFFF
H", "_____" is
displayed.
2. For a "0" value, "0" will be indicated at all the b0 to b31 bits.
