Chapter 6 Applied Instructions 4. The value in S 2 +1 must be between 2 ≦ S 2 +1 ≦ 20; the sign (+,-) and the digits in an integer or decimal number are included but the decimal point in a decimal number and the exponent number are not included. 5. If the value in S 1 is a positive number, the first ASCII code can be stored in D ; if the value in S 1 is a negative number, the sign 16#2D (-) is stored first and then the second ASCII is stored. 6. Decimal format ( S 2 =0) After conversion, the floating-point string in the device D. Decimal .
The value in S 2 +1 must be between 2 ≦ S2+1 ≦ 20; the sign (+,-) and the digits in an integer or decimal number are included but the decimal point in a decimal number and the exponent number are not included. Example 1 Suppose the number of characters is eight. Two floating-point numbers examples are -1.2345678 and 123456. The calculation is as follows. 6_ After the conversion, if the floating-point number is stored in S 2 +1 but if the length exceeds the value in S 2 +1, the instruction rounds off the digits in the decimal number. The floating-point string does not have to fill all of S 2 +1. 6-651 Operand Description S2 0: Decimal format 1:
