Numerical seemed quite popular last time I posted it, so I thought I'd let you guys know about it being on sale in celebration of it gaining a % button as well as "Magic Brackets".
It has received nothing but praise from many influential publications and, best of all, is home grown – the developer is from Adelaide.
Description
Numerical is a calculator without equal. Whether you’re doing simple math, advanced brackets and exponentiation, or need a running history of your previous work, Numerical has the answer.
NOW with Percentage Button, Magic Brackets and Decimal Localisation!
"This could be the best calculator ever." - TUAW
"Exactly what a simple iOS app should be” - BGR
“The way Numerical works makes more sense than Apple’s app for me” - MacStories
“For someone who’s looking for a simple and elegant calculator app that fits iOS 7’s design language, Numerical is a superb choice.” - Beautiful Pixels
“One of my favorite apps I’ve seen this year.” - The Industry
NO EQUAL
The equals button was invented when computers were the size of furniture and it’s time to move on. As you type Numerical displays the answer instantly & your current calculation is always visible.
HISTORY
As you work Numerical automatically saves finished calculations to the History View. When you need to revisit an old problem it's right there waiting for you.
SWIPES
Use easy swipe gestures to undo, redo and save the current calculation.
PERCENTAGE BUTTON
Working out a tip, a discount, or whether the glass is half empty? The new context aware % button has you covered.
MAGIC BRACKETS
Solve complex problems with a single brackets button that intelligently decides whether it should be an open or close bracket. Just tap it and let Numerical figure it out.
COPY AND PASTE
Tap the answer or calculation to copy them elsewhere. You can paste text from any app and Numerical will remove non-maths digits and solve it.
LOCALISED DECIMALS
This calculator now knows what region of the world you're from and how decimals and separators should be presented. It also uses this information to determine how pasted numbers should be interpreted.
SENSIBLE
Numerical knows to display very large answers with scientific notation, and if an answer is approximate (due to recurrence or floating point decay) it will use an “approximately equal to" sign (≈).
SENSIBLE ERRORS
Have you ever divided by zero? Tried to exponentiate a googolplex? If Numerical can’t figure out the answer it will tell you what went wrong in plain english, not just yell ERROR!
What use is a calculator without an equal button? /lame joke
