Shorter version of IF(ISERROR(...))

I'm wondering if there is a way to check if a formula returns an error, and if not, use the value found, without doing the following: ``` =IF(ISERROR(A1/B1), 0, A1/B1) ``` The syntax I'm looking for is something like this: ``` =EQ([value_if_not_error], [value_if_error]) ``` The solution might contain more stuff, `IF` and `ISERROR` is perfectly fine, as long as I avoid having the main function several times in each cell. The reason why I want to do this is that my equations are quite long and the readability is drastically reduced when I have to write the equation twice, or even more (if several `if`s). Is there a simple solution to this?
