SAGA.table_calculus.1: Field Calculator

{"id": "SAGA.table_calculus.1", "title": "Field Calculator", "description": "The table calculator calculates a new attribute from existing attributes based on a mathematical formula. Attributes are addressed by the character 'f' (for 'field') followed by the field number (i.e.: f1, f2, ..., fn) or by the field name in square brackets (e.g.: [Field Name]).<br/>Examples:<br/>- sin(f1) * f2 + f3<br/>- [Population] / [Area]<br/><br/>If the use no-data flag is unchecked and a no-data value appears in a record's input, no calculation is performed for it and the result is set to no-data.<br/><br/>Following operators are available for the formula definition:<br/><table
