6.5.13 Double integer to ASCII code
Input/output Operand Data type
IN VD, ID, QD, MD, SD, SMD, LD, HC, constant, AC, *VD, *AC, *LD Double 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
DTA
：
The instruction converts the double integer to ASCII
characters. (FMT) format specifies the conversion
accuracy of the right of the decimal point.
The conversion result is placed in the 12 successive bytes
from the OUT.
Error conditions:
FMT high four bits value is greater than 0
nnn > 5
The following is the DTA instruction format (FMT) operand definition:
The size of the output buffer is always 12 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.
