Scientific Calculator
Description
This two-line scientific calculator provides the look and feel of a real calculator. With a dedicated line for the equation and another for the result, complex equations can be written with ease. Numbers and simple functions can be input via the keyboard, while more advanced functions are available using the normal calculator buttons.
Current features include:
Trigonometry
Logarithms
Combinations and permutations

Uma calculadora como esta tem que ter um Help ou um manual. O criador do widget não pensou nisto?
Manual?? sério se não sabem mexer em uma calculadora científica simples então por quê baixar?? Enfim, adoro esse widget, acho super útil quando não acho a minha calculadora rs e o melhor é que é praticamente parecida com a minha. Congrats!
62-52.2=9.799999999999997 he, hehe, he, hehe, he
It is very good! He, hehe, he
FINALLY! Someone came up with an easy to read calc. with all the right functions! I also like that when you enter plus (+) , times (x) etc., it actually shows them in the equation. Nicely done!
Wow great work.
cube root of 729 is 8.9999999999999999999998....hahahahahaha
Sashurik and 2operetka, See the bug #302 to fix your simple arith problems. Bearsmalaysia2, This widget does pow(729, 1/3) but hey, you'll see "0.3333333333333333" if you type "javascript:alert(1/3)" in the address bar. So we should round the result anyway.
Thank you so much.
that was my favorite calculator until its got broken. i dont remember whats wrong with it
Easy to read and works well. It has all of the scientific keys you need. My only complaint is where is the percent key?? Thanks for the nice work Opera 10.10
Would be so cool to have a date and time operations, times at least, like this 1:28:31 + 0:45 - 1:08 = 1:28:08 for instance. (H:MM:SS and/or MM:SS format)
It was my favorite calculator until Opera 10.51 comes. After that, some of functions stop responding, including "x" and "/", so this pretty widget becomes unusable. Is there someone who have this problem too, or know how to fix it?
I have experienced the same problem as Haradax; the multiplication and division functions do not work with Opera version 10.52, either.
I have the same problem as Haradax and jereygex; the multiplication and division functions do not work with Opera version 10.53. :-(
Before yesterday I was sent a message to CalcMatic about this problem, and today he answered to me this: "I'll look into this over the weekend. I've neglected my widgets for ages, perhaps this is the excuse I need to restart development on them."
CalcMatic! Please fix this excellent calculator so it works in 10.50 and higher! I used it all the time at work until 2x2 became 2...2 (Err: Number)
Multiply and divide fails to insert the operator, only a blank space. Thus the calculation fails. My Opera info: Version 11.00 Build 1152 Platform Win32 System Windows NT 6.1 R George
he is true! : (( CalcMatic! Please fix this excellent calculator so it works in 10.50 and higher! I used it all the time at work until 2x2 became 2...2 (Err: Number) )) - MossMan & very more bug.... is very bad! ( My Opera info: Opera 11 - last ver. Platform: Intel - Win7 x64
This calculator was the best widget I ever seen! I've been using it in my everyday work, as it's really convenient, and I had the same, but hardware version , at home. This is a big PLEASE to the developer of this application: Please, fix it, I'm sure it shouldn't take you too much time...
