When should I use double instead of decimal?

Question

Aryan Kumar · Answer

In Java, you should use double instead of decimal when you need to store a floating-point number with more precision than
decimal can offer.
double is a 64-bit floating-point number, while decimal is a 16-bit floating-point number. This means that
double can store numbers with more precision than decimal.double is also more efficient than decimal for storing large numbers.
Here is a table summarizing the differences between double and 
decimal in Java:
Feature
double
decimal
Precision
64 bits
16 bits
Range
±1.7976931348623157e+308
±3.4028234663852886e+38
Efficiency
More efficient for storing large numbers
Less efficient for storing large numbers
In general, you should use double when you need to store a floating-point number with more precision than
decimal can offer. You should use decimal when you need to store a floating-point number with a fixed precision, such as currency.
Here are some examples of when you should use double instead of 
decimal:
Storing the value of piStoring the weight of an object in gramsStoring the temperature in CelsiusStoring the area of a circle in square meters
Here are some examples of when you should use decimal:
Storing the price of an item in dollarsStoring the balance of an account in centsStoring the interest rate on a loan in percentStoring the exchange rate between two currencies
