Exlipicit conversion
It is possible to make explicit data conversion of a value (or variable) from one type to another, simply specifying the new data type before the value (or variable).
<target variable> = <type> <source variable> <target variable> = <type> (<source variable>) |
|---|
For example:
; Explict conversion from real to integer int value1 real value2
value2 = real value1 value2 = real(value1) |
Conversion is not allowed on left side of an assignment: in this case, the value is automatically converted into the corresponding assignment target type.
Implicit conversion
As a general rule, when you make an operation between different data types, an implicit conversion can happen to all values according to the first operand/value data type. For example:
int value1 real value2
; Value will be converted in 5.0 type, eg real data type value2 = 5.0 + value1
; 1.2 will be converted in value1, eg int (precision loss) value1 = 1.2 |
