## What is ReadableCalc?

ReadableCalc is a calculator app that displays large numbers—like 3 trillion 500 billion—in readable units.
It’s designed to make extremely large numbers more intuitive at a glance.

Main Features
• Supports four basic operations (+, −, ×, ÷)
• Displays results in English numeric units for easy readability
• Handles decimals and negative numbers
• DEL button for deleting one character at a time
  (Long press to clear the entire expression)
• Long press on expressions or results to copy
• Tap on the “readable” result to toggle display between:
   • Short scale / Long scale / Kanji numerals
   
Additional features in landscape mode:
• “00”, “000”, and “0000” buttons for quickly adding zeros
• “x²” and “x³” buttons for quick exponentiation

Note:
• Numbers exceeding 200 digits may be rounded due to calculation and display limitations.
  Please be cautious if you need high precision.
• Short scale and Long scale support numbers up to 10^198.
• Kanji numeral display supports up to 10^72.
  Larger numbers are shown in Arabic numerals instead.
