Question

Which datatype has two times the precision of float?​

Answer 1

Explanation:

Vertica supports the numeric data type DOUBLE PRECISION , which is the IEEE-754 8-byte floating point type, along with most of the usual floating point operations.

Answer 2

Concept:

Datatypes are used for the declaration of variables. The type and size of data linked with variables are determined by this.

Given:

The datatype has two times the precision of float.

Find:

Which datatype has two times the precision of float?​

Solution:

In computer languages, double is the most frequent data type for assigning values that contain a real or decimal-based number, such as 3.14 for pi. It has single precision.

It has twice the precision of float or two times as much precision. According to IEEE, its floating-point precision is 64-bit and takes 8 bytes for storage which is two times of float.

Hence, double datatype has two times the precision of float.
