25 TYPE CONVERSION FUNCTIONS
25.43 Converting REAL to STRING
• Input a REAL data type value to (s).
• The converted string data is output from (d) as follows.
• The NULL code (00H) is automatically stored at the end (i.e. seventh word) of the converted string.
• The number of digits for an integral part, decimal part, and exponent is fixed, integral part: one digit; decimal part: five digits; exponent: two digits.
• As the second byte, 20H (space) is stored; as the fourth byte, 2EH (.) is stored; and as the 10th byte, 45H (E) is stored automatically.
• As sign data (for integral part), 20H (space) is stored if the input value is positive, and 2DH (-) is stored if the input value is negative.
• The sixth and later digits of the decimal part are rounded off.
• If the number of digits in the input value is less than the number of significant digits, 30H (0) is stored in the decimal part.
• As sign data (for exponent), 2BH (+) is stored if the input value is positive, and 2DH (-) is stored if the input value is negative.
• When the exponent is one digit, 30H (0) is stored in the tens place of the exponent.
