Numeric expressions

In a composed string, if the field can contain a numeric field-value, you can use an arithmetic expression in place of a field-name. I.e. use

+ to add,

- to subtract,

* to multiply,

/ to divide (rounding towards zero) and

() to contain intermediate calculations. For example

{field1*(field2-field3)+1}

where field1, field2 and field3 all supply numeric values.
