How do you remove the decimal of a double in Java?

How do you remove the decimal place of a double in Java?

You can convert the double value into a int value. int x = (int) y where y is your double variable. Then, printing x does not give decimal places ( 15000 instead of 15000.0 ).

How do I turn off decimal places in Java?

Shift the decimal of the given value to the given decimal point by multiplying 10^n. Take the floor of the number and divide the number by 10^n. The final value is the truncated value.

Do doubles in Java have to have decimals?

The double data type is normally the default choice for decimal values. The data type should never be used for precise values, such as currency. Float data type in Java stores a decimal value with 6-7 total digits of precision.

Can we convert double to string in Java?

Which is bigger double or long Java?

3 Answers. If you are storing integers, use Long . Your statement that “Advantage of Using Double is that it gives a more wider range for storing Whole Numbers” is incorrect. Both are 64 bits long, but double has to use some bits for the exponent, leaving fewer bits to represent the magnitude.
