Is the square root of 32 an integer or whole number?

Answer 1

The square root of 32 is 5.65685424949238 (or 5.66 rounded).

An Integer is defined as numbers that can be written without a fractional or decimal component.

A Whole Number is not a mathematical term and can either mean Natural Numbers (0, 1, 2, 3, 4....) or Integers (.... -4, -3, -2, -1, 0, 1, 2, 3, 4....).

ie 12345, 980, 5, and -17 ARE integers

.1213, 3.5, 7.999999 and 3.141592 are NOT integers

Numbers that are qualified by root symbols (ie √2 ) or fractions (ie 5½) are NOT integers they are formulae . However, √ and other similar roots of numbers can become integers if when calculated, they result in integers; in this case √9 = 3.

Note:

Integers are numbers and cannot be a formula, therefore √9 being a formula cannot be an integer so if it was required to be stored in a database on a computer as √9 to preserve it's origin (for example) , then it would have to be kept as text where as the product of the calculation (ie 3) could be kept as such because it is an integer.

The fact that a number is negative or positive does not affect it being or not being an integer. The rules above govern whether it is or is not.

Integers are also a data type (2 bytes) used in computing to store numbers ranging in value from -32,768 to 32,767. (whole numbers only).
