Description
You can easily calculate percentages!
You can calculate percentages easily! Incredibly handy! Below are examples.
- Calculate the post-tax price of 5,500JPY (Japanese consumption tax is 8%): 5,500 + % = 5,940
- Work out the 25% off price of 10,000JPY: 10,000 – 25 % = 7,500
- What is 30% of 30,000JPY?: 30,000 * 40 % = 12,000
- 43% of 120,000,000 people : 120,000,000 * 43 % = 51,600,000
Yes it’s true! This calculator can talk!
It reads out loud the key you’ve pressed or a search result you’ve tapped!
*To enable text-to-speech you need a Japanese text-to-speech software such as N2 TTS.
- Install N2 TTS.
- Open voice setting screen (upon installation it opens automatically. To set later go to Android settings > voice input/output > set text-to-speech)
- Go to ‘Engine’, tick KDDILABS N2 TTS to enable.
- Set default engine to KDDILABS N2 TTS.
- Tap ‘Play Sample’ and check you can hear a Japanese voice.
- Enable text-to-speech in calculacha!
- Touch keys to check for sound.
I pressed the wrong key! Wrong digit! I want to do it again! Press clear button to cancel the last digit. Press and hold to clear all!
‘C’ button is the equivalent to ‘backspace’ key on a computer and deletes the last digit. Press hold to initialize value or calculation.
How many digits?! Input up to 24 digits, display up to 48 digits!
What would be a useful feature? Decimal calculation by typing in a denominator of a fraction.
For 1/2, key in 2/=, 1/3 is 3/=, 1/125 is 125/= and you get your decimals.
Type 1 million quickly! There is a ‘000’ button that lets you key in thousands.
You don’t see it much but this ‘000’ button is useful!
What was the last button I pressed? Displays last calculation on the top left side of the screen.
Displays status such as your calculation (*,/,+,-) and error (E), reset (C), calculation result (=).
I use plus-minus change button a lot.
It’s useful to have!
Displays 48 digits?! Changes font size automatically.
You see it a lot these days. I have built it in, too.
I know the one where you can do the last calculation again by pressing = button!
This function is available on most cauculators. After you pressed 1+5=, press = again and it adds 5 again.
Hold on, are there more hidden functions?!
Indeed, there are! You can change fonts! You can have Pi-chan on your screen! Find them!
You can also tweet. Find it in the menu!
