CX_NUMERIC
Class hierarchy
Description:
This class is used to represent real numbers with a maximum of 16 places before the decimal point and 8 places after.
Instantiation
To create an object of this class with InstantView® , the following possibilities exist:
- Create with the command CreateTransObject(CX_NUMERIC) or CreatePersObject(CX_NUMERIC)
- Direct placement of a real number on the stack similar to integer numbers. The part before the decimal point must be terminated with a ".", so that a real, and not an integer, number is generated. The precision, i.e. the number of decimal places, is also determined. For example, the only difference between "2.1" and "2.100" is that the first number has an accuracy of "1" and the second has an accuracy of "3". The specification "2." produces the real number "2" with an accuracy of "0". If the number of decimal places exceeds the permissible value of "8", only the first 8 are taken into account and work with this accuracy. Negative numbers must be written in round brackets, for example (-2,100).
Attention: The precision for a CX_NUMERIC is implicitly defined when it is created and is then retained for this object. If the CX_NUMERIC is created as a literal (0.000), then the number of specified decimal places determines the precision. If a CX_NUMERIC is created by CreateTransObject/CreatePersObject, then the precision is set to 2 decimal places.
If a new value is assigned via Put, then the type of the operand controls which precision is taken over:
Code example:
Var(num1, num2)
CreateTransObject(CX_NUMERIC) -> num1 // CX_NUMERIC erzeugen
25.5 -> num1 // und Wert zuweisen
.................
55.4 -> num2
................
num1 num2 += // Ergebnis : num1 = 80,9
