Discussion
The number of bits determines directly the range for the respective values:
Number of bits |
Min. value |
Max. value |
---|---|---|
8 bit |
-128 |
127 |
16 bit |
-32768 |
32767 |
32 bit |
-2147483648 |
2147483647 |
The signed integer numbers must always be expressed as a sequence of digits with an optional + or - sign put in front of the number. The literals can be used within expressions wherever an int8, int16 or int32 operand is expected. The type names, in turn, are designated to be used in declarations of data members. For example:
var int32 voltage = 220000; var int16 current = -100;

Type conversions
Chora reacts sensitive when mixing operands of different data types within an operation. To avoid compiler warnings or even errors you can convert the affected operands explicitly by using following conversion operations:

Conversion between signed and unsigned integers. |
Conversion to or from a floating-point value. |
Conversion to or from an enumeration value. |
Conversion to or from a set value. |
Conversion to or from a char value. |
