Caution
1. Handling of floating point
In floating point operations, all data is handled in binary floating point.
Because binary floating point is difficult to understand (requiring a dedicated monitoring method), it is
converted into scientific notation so that monitoring can be easily executed by peripheral equipment.
GX Developer and GOT have the function to directly monitor and display binary floating point.
