: Head number of the devices where the digits numbers for the numerical value to be converted are stored (BIN 16 bits)
: BIN data to be converted (BIN 16/32 bits)
: Head number of the devices where the converted character string will be stored (character string)
Function
STR
(1) Adds a decimal point to the BIN 16-bit data designated by at the location designated by , converts the data to
character string data, and stores it in the area starting from the device number designated by .
(2) The total number of digits that can be designated by is from 2 to 8.
(3) The number of digits that can be designated by +1 as a part of the decimal fraction is from 0 to 5.
However, the number of digits following the decimal point must be smaller than or equal to the total number of digits
minus 3.
(4) BIN data in the range between -32768 and 32767 can be designated at .
(5) After conversion, character string data is stored at the device number or later device number as indicated below:
(a) The sign "20
H
" (space) will be stored if the BIN data is positive, and the sign "2D
H
" (minus sign) will be stored if it is
negative.
