# What happens when you add an int to a double? ### What happens when you add an int to a double?

When one operand is an int and the other is a double, Java creates a new temporary value that is the double version of the int operand. For example, suppose that we are adding dd + ii where ii is an int variable. ... It then adds this temporary value to the other double operand.

### Which conversion is possible in C?

The type conversion process in C is basically converting one type of data type to other to perform some operation. The conversion is done only between those datatypes wherein the conversion is possible ex – char to int and vice versa.

### What is double in C?

A double is a data type in C language that stores high-precision floating-point data or numbers in computer memory. It is called double data type because it can hold the double size of data compared to the float data type. A double has 8 bytes, which is equal to 64 bits in size.

### Is an int double A double time?

The type of the variable will automatically convert when it needs to - the result of multiplying a double and an int is another double.

### Which type conversion is not possible in C?

Explanation: None. 3. Which type of conversion is NOT accepted? Explanation: Conversion of a float to pointer type is not allowed.

### What is type conversion in C with example?

Type casting refers to changing an variable of one data type into another. The compiler will automatically change one type of data into another if it makes sense. For instance, if you assign an integer value to a floating-point variable, the compiler will convert the int to a float.

### What's the difference between double and float?

What's the difference ? double has 2x more precision then float. float is a 32 bit IEEE 754 single precision Floating Point Number1 bit for the sign, (8 bits for the exponent, and 23* for the value), i.e. float has 7 decimal digits of precision.

### What is double data type example?

You can use exponential notation in DOUBLE literals or when casting from STRING , for example 1.

### When to convert an int to a double in Java?

Since double has longer range than int data type, java automatically converts int value to double when the int value is assigned to double. 1. Java implicit conversion from int to double without typecasting.

### Is it possible to convert an integer to a double in C + +?

if i'm not wrong you can directly assign an integer to a double in c++, there's no need to do an explicit casting. It's called "typecasting". chandra.rajat is correct in many cases. The compiler will figure out the typecasting above without being told and unlike Java, C++ doesn't demand all of the explicit conversions.

### Why are int conversions not implemented in strong typed languages?

This is the primary reason why implicit conversion from double to int is not implemented in a lot of strong-typed languages. The conversion of int to double actually increases the amount of information in the type, and can thus always be done safely.

### Why do you need to explicit cast from INT to double?

The range of double is wider than int. That's why you need explicit cast. Because of the same reason you can't implicitly cast from long to int: Implicit casting is only available when you're guaranteed that a loss of data will not occur as a result of a conversion. So you could cast an integer to a double, or an integer to a long data type.
