Is i an irrational number?
On the one hand, i(=√−1) cannot be expressed as a ratio of integers, so, by definition, i is not rational ⟺i is irrational. However, the set of irrational numbers, J=R∖Q is defined to be the set of all real numbers that are not in Q, but, clearly, i∉R, so it must be that i∉J, so i is not irrational.
What kind of number is a negative number?
Negative numbers: Real numbers that are less than zero. Because zero itself has no sign, neither the positive numbers nor the negative numbers include zero. When zero is a possibility, the following terms are often used: Non-negative numbers: Real numbers that are greater than or equal to zero.

What type of number is the number?
Numbers include: Natural numbers (whole numbers), integers, rationals, irrational, real numbers, imaginary, and complex numbers. Natural numbers are counting numbers and whole numbers. They are 1, 2, 3, 4, and sometimes include 0.
Which is a real number and which is an imaginary number?
The symbol R represents real numbers. Numbers other than real numbers are imaginary or complex numbers. When we square an imaginary number, it gives a negative result, which means it is a square root of a negative number, for example, √-2 and √-5.

Natural numbers or counting numbers are the most basic types of numbers you learned for the first time as toddlers. They start from 1 and go to infinity, i.e., 1, 2, 3, 4, 5, 6, and so on. They are also called positive integers.
What kind of numbers are called real numbers?
All integers are real numbers, but not all real numbers are integers. Real numbers include all the integers, whole numbers, fractions, repeating decimals, terminating decimals, and so on. The symbol R represents real numbers.
