Real Numbers are used everywhere!
-My family has (3) cars.
-We lost 5 kids. (-5)
Decimal numbers are real numbers. In C and C++ we use the float, double and long double data types to represent real numbers.
Real numbers are all numbers which do not contain "i", when "i" represents the square root of -1. All numbers which do contain "i" are "imaginary numbers" and are not real numbers. This means that all numbers you'd ordinarily use are real numbers - all the counting numbers (integers) and all decimals are real numbers. So in answer to your question, all the real numbers that are not whole numbers are all the decimal numbers - including irrational decimals such as pi.
well you use them for math
Jeopardy.
For computations and Measurement ;))
natural numbers
In the real world you can use the order of rational numbers. This is used a lot in math.
Yes, all natural numbers are real numbers. Natural numbers are a subset of real numbers, so not all real numbers are natural numbers.
No, not all numbers are real numbers. Real numbers include all rational and irrational numbers, but there are also complex numbers that are not considered real numbers.
