Revisit the spacing in binary operators

[ronisbr]

Hi!

Sometimes, when writing large equations, the rule of adding spacing to all binary operators can lead to a very verbose text. Compare, for example:

aux_U += P[n + 1, m + 1] * (C[n + 1, m + 1] * cos_mλ + S[n + 1, m + 1] * sin_mλ)
aux_U += P[n+1, m+1] * (C[n+1, m+1]*cos_mλ + S[n+1, m+1]*sin_mλ)

IMHO the latter is much more readable and understandable because the spacing is used to separate the factors.

I would say I find the former easier to read. It's definitely worth calling out this style guide provides guidelines and not rules.
