14.9 BTOA (Conversion: BIN → ASCII)
Example 12) Converting 32-bit single-precision floating point real number data (2
data) to exponential notation ASCII data (10 digits x 2)
The low byte of DT100 is set as the beginning of the storage area. 2 digits after the decimal
point. Exponential notation is used. For a positive number, a space is inserted.

Example 13) Converting 32-bit single-precision floating point real number data (2
data) to floating point ASCII data or exponential notation ASCII data (9 digits x 2)
The high byte of DT100 is set as the beginning of the storage area. It is stored left-aligned (low
word side). The data is converted to 7 significant figure floating point ASCII data before storing.
● The conversion is either to floating point ASCII data or to exponential notation ASCII data,
whichever is shorter.
