Question

Computers and programs use double floats when they need?

Answer 1

Ans: -

In programming languages there are data types which are used for declaring variables. All the data types have different storage space and these data types are used according to the required criteria when they are needed in different programs. So, one these data types are float data type which is used in declaring the decimal type values. In C programming language the float data type has the precision of six decimal values. Double float is used for performing complex arithmetic operations faster.

float data types values can be declared when there is requirement of multiple floating-point values.

For the less consumption and efficient use of the memory the float can be used. For example, while storing a large size arrays of numbers to reduce the memory use by the program.

In most of the cases double data types is frequently used by the computers and programs but float can be used to make a program less complex because float value has fewer decimal places than the double. It also saves the size of the memory. But double float data type is used for getting the more complex decimal values accurately and efficiently. It uses more space than the float data type values

The float can be also used due to the hardware specifications when hardware supports the single float-point values precision than the double floating-point precision. In this case the float can be used by the computers and programs.

When any computer application is performing many arithmetic operations, which requires floating point values then the float can be used.

In c programming language the double float has precision of 16 decimal values. Double floats can be used when the accurate value is required in decimal format.
