When I wrote my program I only used real numbers and integers which are the only kind of numbers there are.

A computer is not able to use real numbers. What's called "real" in programs is only an element of the rational numbers.

Correctly. The computer can only operate on the numbers that it represents in the form of a periodic fraction. These numbers are called rational numbers. Real numbers are rational numbers + irrational. To display an irrational number, the computer first converts it into a rational number with a large fractional part period. The rest cuts off.

Word play, how cute.

I have a number x = 5 of the abscissa and y = -3 ordinate. How to write in the form of a complex number?

The Cartesian coordinates are in this case r (=real axis) and i (=imaginary axis). If z=5-3i then it would be a point P(5|-3).

And what was before the Big Bang?

Nothing, I guess. Specially it was no time before the big bang, if time was created in the very first moment of the big bang. Saint Augustinus said the question "What was before god created the world?" is a senseless question, because god created everything, time too. There was no "before" before god did so. So we are not able to ask this. The word (logos) of creation is a timeless word (logos).

Nonsense. Any number with a fraction is a real number.

All natural numbers and all fractions of natural numbers are real numbers too, but not every real number is such a fraction. A computer approximates an integer numerator and integer denominator in case of Sqrt(2) or pi for example.

No...
There is an absolutely clear answer, according to Fundamental Physics:
This answer was given by British scientist Stephen Hawking ...

=============================
Before the "Big Bang" there was no TIME...
That's all

======================================================
I ask you not to upload clips ...
It is not interesting...
Here we are talking about Mathematics and Physics

We live and use numbers ...
But we do not always understand what these figures are?

1. Natural numbers ..
In Science, the symbol N
N = 1 2 3 4 5 ....

-------------------------------------------------- -------------------------------------
2. Whole numbers ..
In Science, the symbol Q
Q = all natural numbers + 0 + natural numbers with the sign "-"
Q = ........ -5 -4 -3 -2 -1 0 1 2 3 4 5 ............

-------------------------------------------------- -------------------------------------
3. Rational numbers ..
In Science they are denoted by the symbol of R
R = Q / N
The sign of a rational number is that you can write it in the form of an infinite periodic fraction
For example:
R = 1/3 = 0.3333 .. = 0 (3)

-------------------------------------------------- -------------------------------------
4. irRational numbers ..
In Science they are denoted by the symbol of I
A sign of an irrational number is that you can not write it as an infinite periodic fraction R = Q / N
For example:
- pi = 3.14 ...
- exp = 2.71...
- In addition ... In Science there are so-called "convergent series", for example the Taylor series, the Fourier expansion ... These are also irrational numbers, but it is difficult to show them

==================================================
All these numbers in Science are called "real" .....


Besides...
In science there are "complex numbers" ....


==========================================================
The topic will be continued, if interested ...

1.414, the square root of 2 is in the speed of light. How did the square root of two get into that? Numbers are cool but prime numbers scare me.

Do not be scared .. Russian will teach you
Just behave properly

The Inverse Square Law is more than useful and Lambda equals one over period time. Lambda has nothing to do with the inverse square law but I had to mention both to tickle your brains.

So put your "brains" in your ass, and then learn how to make money

The answer is "4."

Another such spam - I will send to the Ignore

Please answer my question

Selivan, come check out the Flame Zone.

That's where all the really intelligent posters hang out.

I ask the "old-timer" of this forum to answer my question ...
Otherwise, you will be sent to the Ignore

I give you 1 minute
