I am trying to make a calculator app in Android Studio and want to store the numerical value in a variable.

What is the longest data type in Java which can store the max amount of decimals and what is its limit?

CodePudding user response：

looks like you need Big classes, like BigInteger and BigDecimal. also inspect other useful for your case classes extending Number:

AtomicInteger, AtomicLong, BigDecimal, BigInteger, Byte, Double, DoubleAccumulator, DoubleAdder, Float, Half, Integer, Long, LongAccumulator, LongAdder, Rational, Short

question about max size of these "Bigs" is answered HERE
