Description
Arithmetic operations of ovariables: first they are merged by index columns, then the operation is performed for the Result.x and Result.y columns.
If one of the expressions is numeric, it is first transformed to ovariable.
Code
⇤--#: . You cannot use code "callGeneric(e2, e1)" with other order than original, because some functions like "/" and "-" cannot be reordered. --Jouni 23:30, 1 July 2012 (EEST) (type: truth; paradigms: science: attack)
