This review was originally posted on VersionTracker.com.<br />...i reviewed this before. it's a MUST. it deserves nothing but 5 stars. most often, when a wanna do a quick calculation, i just type it to - the terminal - safaris url-bar - an email - any cocoa textfield - a sticky - ... and hit [command]-[=] instead of opening the apple calculator. if it would lookup and convert currencies, i wouldn't use the calculator at all. otoh, the syntax would be so complicated... would it?

Enter CalcService.</p> <p>I need to position some element in CSS, so I can enter the width of the two elements preceding it, (a + b) select the values, and select Calculate & Replace.</p> <p><b>Boom.</b></p> <p><b><i>Sweet!</i></b></p>

Developer’s Description

By DEVONtechnologies

Calculator service with trig/log/exp functions & constants.

This service calculates the result of a selected formula within all Cocoa-applications (e.g. Textedit, Mail, Stickies, Notes, ProjectBuilder, Fire, OmniWeb or TeXShop) and appends the result to the formula or replaces the formula with the result. In addition there's the possibility to display the result in a panel without modifying the text. So there's no more need to start Calculator or stuff like that if you only want to calculate some values immediately within text view or dialog fields.
