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 iTNC converts the absolute amount of the number

without putting a sign before the string. For algebraically signed notation, the

iTNC 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 iTNC 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).
