Conversion functions int8

Contents

concept

  1. int8 is a 8 bits (1 byte) signed integer value type.
  2. int8() is a function converting data items or units of other value types to the int8 value type.

The next topics on this page describe the int8() function.

syntax

definition

int8(a) results in a 8 bits(1 byte) signed integer item converted from item a. The function results for:

  • integer data items: the integer value is interpreted as int8 value, if the value exceeds the allowed value range for the int8 value type, the resulting value will be null;
  • float32/64 data items: the value before the decimal point (so 1.9 will be rounded off to 1 and 2.0 to 2). If the value exceeds the allowed value range for the int8 value type, the resulting value will be null;
  • boolean data items: 1 for True values and 0 for False values;
  • string data items, if the value starts with an allowed numeric value for the value type, this value is converted to a int8 value type. Other characters after the numeric values are ignored. If the string does not start with an allowed numeric value for the value type, the resulting value will be null;
  • units, a 8 bits(1 byte) signed integer unit of the converted unit.

example

1. parameter<int8> int8Numeric1 := int8(1);
2. parameter<int8> int8Numeric1 := 1b;

3. attribute<int8> int8A (ADomain) := int8(A);    
4. attribute<int8> int8B (ADomain) := int8(B);
A(float32) B(string) int8A int8B
0 'Hello' 0 null
1 'Test' 1 null
1000000 null null null
-2.5 'Two words' -2 null
99.9 '88a' 99 88
