DESTR / Floating Point to Character String Conversion
Outline
This instruction converts the binary floating decimal point data into character string (ASCII code) in a specified
number of digits. You can also use the STR instruction for converting BIN data into character string (ASCII
code).

code).
→ As for character string, refer to FX Structured Programming Manual [Device & Common].
→ As for handling of floating decimal point, refer to FX Structured Programming Manual [Device &
Common].
→ As for STR instruction, see section 26.1.
