6.5.12 Integer to ASCII code
Input/output Operand
Data type
IN VW, IW, QW, MW, SW, SMW, LW, AIW, T, C, AC, constant, *VD, *LD, *AC Integer
FMT VB, IB, QB, MB, SB, SMB, LB, AC, constant, *VD, *LD, *AC byte
OUT VB, IB, QB, MB, SB, SMB, LB, *VD, *LD, *AC byte
ITA:The instruction converts the integer word to ASCII
characters. (FMT) format specifies the conversion
accuracy of the right of the decimal point.
The conversion result is placed in the 8 successive bytes
from the OUT.ASCII character number is always 8
characters.
Error condition:
nnn > 5
The following is the ITA instruction format (FMT) operand definition:
The size of the output buffer is always 8 bytes.nnn = The number of characters of the
right of the decimal point.The effective range of the NNN is from 0 to 5.NNN is equal
to 0, the output shows no decimal point.When the NNN value is greater than 5 ,the
output string is filled with ASCII space characters.The C bit specifies using a comma (C
= 1) or a decimal point (C = 0).High 4 bits must be 0.
Prompt: The output according to the following rules
1.Positive number is written to output buffer without a sign.
2.Negative number is written to the output buffer with
“
-
”
.
3.The starting zero on the left of the decimal point is compressed.
4.The value in the output string must be aligned to the right.
