7.11 Character string processing instructions
7.11.11 ESTR, ESTRP
For example, in a case where there are 8 digits in total, with 3 digits in the decimal fraction part, and the value designated
is -1.23456, the operation result would be stored in the area starting from in the following manner:
(a) The total number of digits that can be designated by +1 is as shown below:
When the number of decimal fraction digits is "0"
.........................Number of digits (max.: 24) 2
When the number of decimal fraction digits is other than "0"
.........................Number of digits (max.: 24) (Number of decimal fraction digits + 3)
(b) The number of digits of decimal fraction part that can be designated by +2 is from 0 to 7.
However, the number of digits following the decimal point must be smaller than or equal to the total number of digits
minus 3.
(c) The converted character string data is stored at the area starting from the device number as indicated below:
1) The sign "20
H
" (space) will be stored if the 32-bit floating decimal point type real number is positive, and the sign
"2D
H
" (minus sign) will be stored if it is negative.
2) If the decimal fraction part of a 32-bit floating point real number data is out of the range of the digits of decimal
fraction part, the lower decimal values will be rounded off.
