Module 9051 Conversion from binary → ASCII
Module 9051 converts a binary numerical value into an ASCII-coded decimal
number in the specified format and saves it as a string in the specified
address. The number is interpreted as a two’s complement. For algebraically
unsigned notation, the control converts the absolute amount of the number
without putting a sign before the string. For algebraically signed notation, the
control sets an algebraic sign ("+" or "–") in front of the string in any event. For
notation in inches, the number is divided by 25.4 before conversion. If the
number has more decimal places than the total that you have specified for the
number of places before and after the decimal point, then the control omits
the most highly significant decimal places. In right-aligned notation leading
zeros before the decimal point are replaced by blanks; in left-aligned notation
they are suppressed. Trailing zeroes after the decimal point are always
converted.
Constraints:
The decimal character is defined by Machine Parameter MP7280 as a comma
(MP7280 = 0) or a period (MP7280 = 1).
Call:
PS B/W/D/K <Numerical value to be converted>
PS B/W/D/K <Display modes, bit-encoded>
Bit #1/#0: Format
00: Sign and number left-aligned
1: Sign left-aligned, number right-aligned
10: Sign and number right-aligned
11: Not permitted
Bit #2: Display converted to INCH
Bit #3: Display with sign
PS B/W/D/K <Number of places after the decimal point>
PS B/W/D/K <Number of places before the decimal point>
PS B/W/D/K <String address in which the control saves the ASCII-coded
decimal number>
