S1+1 S1
32-bit floating-point real number
For example, if the total number of digits is 8, and the number of digits in decimal fraction is 3, and "-1.23456" is designated,
the following will be stored in the area starting from (D).
S2

S2+1
8
S2+2 3
S1+1 S1
-1.23456
32-bit floating-point real number
 The total number of digits that can be designated by (S2+1) is as follows:
- When the number of digits in decimal fraction is "0": Number of digits (max.: 24) ≥ 2
- When the number of digits in decimal fraction is other than "0": Number of digits (max.: 24) ≥ (number of digits in deci-
mal fraction + 3)
 The number of digits in decimal fraction that can be designated by (S2+2) is from 0 to 7 digits. However, the number of dig-
its in decimal fraction must be less than or equal to the total number of digits minus 3.
