In common use, yes.
so 0.25, 3.156 are real.
But it's possible to have decimal imaginary values, and decimal complex values. These are common in (for example) alternating current electrical circuits.
The symbol i represents the square root of -1, commonly written as j in electrical calculation.
Thus we get 0.25i, 3.156i (imaginary numbers)
and
2-0.25i, 6.3+3.156i (complex numbers).

Can a decimal be a real number?
All decimals are real numbers and all real numbers can be expressed as decimals.
What are decimals real numbers natural numbers integers or whole numbers?
Decimals are real numbers. Furthermore, integers and whole numbers are the same thing.
Are decimals considered a natural number?
No. Decimals come under "real numbers" and not natural numbers as natural numbers are positive whole numbers i.e., positive integers.
Is a recurring decimal a real number?
Yes. All decimals are real numbers.
Do decimals and whole numbers use Roman numerals?
No,decimal numbers and whole numbers are not counted in Roman Numerals,ROman nUmerals are meant only for natural Numbers.

What do decimals mean in mathematics?
Real numbers
Are negatives and decimals the same?
No. Negative numbers form a set of numbers. Numbers written as decimals is a notation for writing numbers. Different things.Negative numbers can be written as decimals, fractions, complex numbers, etc.Numbers written as decimals can be either negative numbers, zero, or positive numbers. They can also be integer numbers or real numbers.
Are decimals considered a natural number?
No. Decimals come under "real numbers" and not natural numbers as natural numbers are positive whole numbers i.e., positive integers.
Are all integers real numbers?
Every integers are real numbers.more precisely, integers are the subset of R, the set of real numbers.They are whole numbers with no decimals or fractions
Is a recurring decimal a real number?
Yes. All decimals are real numbers.
What are the real numbers that is not a whole number?
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.
Is negative 11.5 a real number?
Yes. In general, real numbers include negative numbers; they also include numbers that have decimals.
How can you compare two real numbers on the number line?
Real numbers are compared by distance from zero That means converting numbers to decimals to determine which number is greater and putting these decimals in order from least to greatest or ordering the corresponding real numbers. I posted a link as an example.
Do decimals and whole numbers use Roman numerals?
No,decimal numbers and whole numbers are not counted in Roman Numerals,ROman nUmerals are meant only for natural Numbers.
Is infinity counted as a real or imaginery number?
real numbers are neverending
