can u explain me the meaning with example "integer" and "real" number?

Question

thank you sir

Answer 1

a real number is any number including decimals and repeating numbers.

ex. 2, 3.653245, 3.1415, 8/57.

integers are whole numbers including negatives.

-4, -4524, 3245, 2, 454

Answer 2

Integers are whole numbers. 1, 2, 3. No fractions like halves or fourths and no decimals. 672 is an integer and a real number. 672.4 is a real number but not an integer. You didn't ask, but imaginary numbers have neverending and never repeating decimals; the square root of 2 is an imaginary number.

All integers are real numbers but not all real numbers are integers.

Not sir. I'm female. Girls can do math too.

Answer 3

The basic question has been answered, with examples, The term "real number" is a retronym coined in response to "imaginary number". Since you asked the question on the "software" category, I can assume you are concerned with programming languages and computers. Here the terms take on a real significance (no pun intended). Integer arithmetic is exact, but real arithmetic is approximate. To minimize errors, never declare a variable as "real" when "integer" will suffice.

Answer 4

Integer number is the one without decimal point. For example
12, 435, 98.
These are integers. Real numbers also called floating point numbers has deceimal point. For example
12.45, 45.2, 987.45

Answer 5

Integers are negative numbers like 0,-1,-2,-3....

And real numbers are all numbers. 1/3, -2, 0, 1, 2.34
Example: negative, rational,irrational,whole, natural, Integers...

Answer 6

Integers are negative,zero and positive numbers.
ex. Integers, Z...-3,-2,-1,0,1,2,3...

Real #'s consist of
1. Rational #'s Integers, fractions, decimals that terminate or repeat pattern.
ex. Decimals that terminate: 0.12
ex. repeating pattern: 1/3 or .333

2. Irrational #'s decimals representation keep going on forever but doesn't have repeating pattern.
ex. pie,square root of 2 and 3 square root of 13

Answer 7

I think integers are negative and postive whole numbers eg -1 -2....1 2 3

Real; numbers are all the numbers including decimals , fractions...etc

Answer 8

H there !
The integer numbers are the "zero", "the real numbers" and the "negatives of the natural numbers".
Real numbers are the common natural whole numbers 1.2.3,4,5 etc.etc...

Best wishes !

Answer 9

Integer is number which not have decimals, for example

1 3 100 23 -6

this is not integer

1/2 0.5 2.333 1000.1

Answer 10

easy stuff...i take advanced math class in school...
and integer is is a set of numers like if you say -3,-2,-1,0,1,2,3...this can be positive or negative numbers....

while whole numbers or real as you call them can only be positive like 1.2.3....

it's easy stuff...
