F75_BIN2A

Converts the 16-bit data specified by s1 to ASCII codes that express the equivalent decimal value. The converted result is stored in the area starting from the 16-bit area specified by d as specified by s2. Specify the number of bytes in decimal number in s2. (This specification cannot be made with BCD data.)

Parameters

Input

s1 (WORD, INT, UINT)

16-bit area to be converted (source)

s2_Number (INT)

specifies number of bytes used to express destination data (ASCII codes)

Output

d_Start (WORD)

16-bit area for storing ASCII codes (destination)

Remarks

• Instead of using this F instruction, we recommend using the corresponding FP7 instruction: FP_DEC_TO_ASCII

• If a positive number is converted, the "+" sign is not converted.

• When a negative number is converted, the "-" sign is also converted to ASCII code (ASCII HEX code: 16#2D).

• If the area specified by s2 is more than that required by the converted data, the ASCII code for "SPACE" (ASCII HEX code: 16#20) is stored in the extra area.

• Data is stored in the direction towards the final address, so the position of the ASCII code may change, depending on the size of the data storage area.

• 

  1.  (1) When s2 = 8 (8 bytes)
  2.  (2) ASCII code
  3.  (3) Extra bytes
  4.  (4) Range specified by s2

• If the number of bytes of ASCII codes following conversion (including the minus sign) is larger than the number of bytes specified by the s2, an operation error occurs. Make sure the sign is taken into consideration when specifying the object of conversion for the s2.

• The following illustrations show conversions from 16-bit decimal data to ASCII codes.

  • When a negative number is converted:

    

    1.  (1) 16-bit data
    2.  (2) F75_BIN2A instruction execution
    3.  (3) Converted result
    4.  (4) ASCII code
    5.  (5) Extra bytes
    6.  (6) Range specified by s2 (6 bytes)

  • When a positive number is converted

    

    1.  (1) bit data
    2.  (2) F75_BIN2A instruction execution
    3.  (3) Converted result
    4.  (4) ASCII code
    5.  (5) Extra bytes
    6.  (6) Range specified by s2 (6 bytes)

• Decimal characters to express ASCII HEX code:

  Decimal characters	ASCII HEX code
  SPACE - 0 1 2 3 4 5 6 7 8 9	16#20 16#2D 16#30 16#31 16#32 16#33 16#34 16#35 16#36 16#37 16#38 16#39

Error flags

sys_bIsOperationErrorHold (turns to TRUE and remains TRUE)

• if the number of bytes specified by s2 exceeds the area specified by d.

• if the data specified by s2 is recognized as "0".

• if the converted result exceeds the area specified by d.

• if the number of bytes of converted result exceeds the number of bytes specified by s2.

sys_bIsOperationErrorNonHold (turns to TRUE for one scan)

• if the number of bytes specified by s2 exceeds the area specified by d.

• if the data specified by s2 is recognized as "0".

• if the converted result exceeds the area specified by d.

• if the number of bytes of converted result exceeds the number of bytes specified by s2.
