What is double in C? In this topic, we will discuss the double data type in the C programming language. The C language provides four main data types such as int, char, float, and float. The int data type is used to store an integer, the char data type is used to store character type, and the float data type is used to store decimal type data with single precision. 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.

In double data type, the 1 bit for sign representation, 11 Was ist ein double C++? for the exponent and the remaining 52 bits used for the mantissa. The range of double is 1. Double data can be represents in real number 1, 10decimals 0. It can hold approximately 15 to 16 digits before and after the decimal point. Declaration and Initialization of double variable Declaration of double variable: To declare a double variable inwe need to specify the data type and a variable name.
Program to convert feet into meter using the double data type Let's consider an example to pass the double data number as the parameter to a function and then convert the feet into meters.
It is a predefined data type or keyword whose meaning and name cannot be changed.
unterschied zwischen double und float..
The float data type is faster than double because its range is small. It can hold approximately 7 digits. Furthermore, the range of float data type is 1.
It is also a predefined data type whose meaning and name cannot be changed. It is slower as compared to the float data type because its size is big.
It can holds accommodate Was ist ein double C++? to 17 digits.
And the range of double data is 5. Conclusion: A double data type is double-precision floating pointing data.
It can hold the double size of the data compared to the float data type because double takes 64 bits in computer memory, which is larger than 32 bits of float data type. It is usually used to deal with the huge computation of numbers and mantissa for precision makes.
Many programmers choose the double data type because it gives accurate decimal-related results for complex numbers. Javatpoint Services JavaTpoint offers too many high quality services.
