Logical conditions might easily become the most important part of web calculators in general. See what Calculoid can do in this regard.

In Calculoid, setting up logical conditions is used to show/hide specific fields of a calculator. When conditions for a specific field come true, the field is shown (white field), otherwise, it's hidden (gray field).

Such a behavior is practical when some fields in a calculator are only relevant when specific numerical values are entered into some other fields (such as a slider, gauge, formula...), i.e. the data input is only required under specific conditions but not otherwise.
