C প্রোগ্রামিং এর double Data Type সম্পর্কে আলোচনা

The double Data Type
In the C language, a floating-point number can also be represented by another data type, called the double data type. In other words, you can specify a variable by the double keyword, and assign the variable a floating-point number.

The difference between a double data type and a float data type is that the former normally uses twice as many bits as the latter. Therefore, a double floating-point number is of at least 10 digits of precision, although the ANSI standard does not specify it for the double data type.

In Chapter, "More Operators," you'll learn to use the sizeof operator to obtain the length of a data type, such as char, int, float, or double, specified on your computer system.

If life were a straight line, it would be very boring. The same thing is true for programming. It would be too dull if the statements in your program could only be executed in the order in which they appear.

Basically, the math functions provided by the C language can be classified into three groups:

Trigonometric and hyperbolic functions, such as acos(), cos(), and cosh().

Enabling or Disabling the Sign Bit

As you know, it's very easy to express a negative number in decimal. All you need to do is put a minus sign in front of the absolute value of the number. But how does the computer represent a negative number in the binary format?
