"to a first approximation" definition
1. to a first approximation - When one is doing certain numerical computations, an approximate solution may be computed by any of several heuristic methods, then refined to a final value. By using the starting point of a first approximation of the answer, one can write an algorithm that converges more quickly to the correct result.
2. to a first approximation - In jargon, a preface to any comment that indicates that the comment is only approximately true
