next higher available size.

Data Type Conversion

Values of one type can sometimes be converted to a different type according
to the following table:

Data Type Deduction

Input signals have a defined type as can be seen in the type column of the Vari-
able Explorer. The types of intermediate results of a calculation formula are
chosen automatically depending on the input types and the applied operations.
This process is called type deduction.
