Input: dual = 3452.234Output: 3452Input: twin = 98.23Output: 98Double: The twin data form is a double-precision 64-bit IEEE 754 floating-point. That is value variety is endless. The double data type is generally used because that decimal values, similar to float. The twin data form also must never be provided for specific values, such together currency. That default value is 0.0.Example: double d1 = 10.5


Integer: The essence or int data kind is a 32-bit signed two’s enhance integer. That is value-range lies in between – 2,147,483,648 (-2^31) to 2,147,483,647 (2^31 -1) (inclusive). That is minimum value is – 2,147,483,648 and also maximum worth is 2,147,483,647. That is default value is 0. The int data kind is generally used together a default data kind for integral worths unless if there is no problem around memory.Example: int a = 10

Approaches

There are many approaches to carry out the counter of dual datatype to Integer (int) datatype. A couple of of them are noted below.Using TypeCastingUsing Double.intValue() methodUsing Math.round() method

Approach 1 – making use of TypeCasting

This technique is very basic and user-friendly.Syntax –double data = 3452.345int worth = (int)data;Example:

Approach 2 – utilizing Double.intValue() method

This an approach is comparable to typecasting method. The main difference between typecasting an approach and this method is that typecasting technique is an explicit method, and also this method is a Wrapper class dual truncates every digits ~ the decimal point.


Syntax:double data = 3452.345Double newData = new Double(data);int worth = newData.intValue();Example:
OutputDouble - 3452.345Double - 3452

Approach 3 – making use of Math.round() method

Math.round() accepts a double value and also converts it into the nearest lengthy value by including 0.5 to the value and also trimming that decimal points. The lengthy value can then be convert to an int making use of typecasting.

Syntax:long Math.Round(Double doubleValue);Example:
Note – Here you deserve to see that the Math.round() method converts the double to an essence by round off off the number to the nearest integer.For example – 10.6 will certainly be convert to 11 using Math.round() an approach and 1ill be convert to 10 utilizing typecasting or Double.intValue() method.
