A double type variable is a 64-bit floating data type
The double is a fundamental data type built into the compiler and used to define numeric variables holding numbers with decimal points.
Par ailleurs, How many bytes is a double in C?
Floating-Point Types
| Type | Storage size | Precision |
|---|---|---|
| float | 4 byte | 6 decimal places |
| double | 8 byte | 15 decimal places |
| long double | 10 byte | 19 decimal places |
Ainsi What is a long double in C? In C and related programming languages, long double refers to a floating-point data type that is often more precise than double precision though the language standard only requires it to be at least as precise as double .
What is float and double in C? Float is a 32-bit floating-point data type.1-bit for the sign, 8-bit for exponent, 23-bit for the value or mantissa. Double is a 64-bit floating-point data type. 1-bit for the sign, 11-bit for exponent, 52-bit for the value or mantissa. The float variable requires 4-bytes of memory space.
Or, What is the double of 4?
The double of 4 is 8.

| long double | 16 bytes | 16 bytes |
What is the size of data types in C?
It is also possible that the integer size is 32-bits or 4 bytes for a 64-bits processor . It entirely depends on the type of compiler.

Can we use long double in C?
%Lf format specifier for long double
%lf and %Lf plays different role in printf. So, we should use %Lf format specifier for printing a long double value.
How big is a long double?
A long double typically only uses 10 bytes, but due to alignment may actually take up 12 or 16 (depending on the compiler and options) bytes in a structure. The 10 byte long double provides a 64-bit mantissa; this is very convenient for when you want to store 64 bit integers in floating point without loss of precision.
What do you use for double in C?
We can print the double value using both %f and %lf format specifier because printf treats both float and double are same. So, we can use both %f and %lf to print a double value.
What does %f mean C?
Format Specifiers in C
| Specifier | Used For |
|---|---|
| %f | a floating point number for floats |
| %u | int unsigned decimal |
| %e | a floating point number in scientific notation |
| %E | a floating point number in scientific notation |

What is a double data?
double: The double data type is a double-precision 64-bit IEEE 754 floating point. Its range of values is beyond the scope of this discussion, but is specified in the Floating-Point Types, Formats, and Values section of the Java Language Specification. For decimal values, this data type is generally the default choice.
What is type double?
Double (double-precision floating-point) variables are stored as IEEE 64-bit (8-byte) floating-point numbers ranging in value from: -1.79769313486231E308 to -4.94065645841247E-324 for negative values. 4.94065645841247E-324 to 1.79769313486232E308 for positive values.
What is double data type example?
For example, to store the annual salary of the CEO of a company, double will be a more accurate choice. All trigonometric functions like sin, cos, tan, mathematical functions like sqrt return double values.
