The Infinity Symbol in Scilab

Fancy bringing infinity into your calculations? With Scilab, it's as simple as using the constant %inf.

%inf

This powerful symbol can be harnessed within any mathematical equation or expression.

There's a golden rule to remember, though. When jotting down infinity (∞) in your calculations, always stick with the constant %inf. Meanwhile, when Scilab spits out the results of these calculations, it uses the symbol Inf to indicate the infinite.

Let's dive into some real-world examples.

When assigning the infinity symbol (∞) to the variable x, we lean on our trusty constant %inf.

x = %inf

And just like that, the symbol Inf is tucked away inside the variable x.

disp(x)

Inf

Negative infinity (-∞), you ask? No problem, just scribble down -%inf.

x = -%inf

This time around, the symbol -Inf finds a home in the variable x.

disp(x)

-Inf

But what happens if we multiply infinity by -1?

y = -1 * %inf

Voila! The symbol -Inf, or negative infinity (-∞), is snugly stored in the variable y.

disp(y)

-Inf

The constant %inf is versatile and can be employed in any mathematical operation. Scilab sticks to all the big-league rules of maths when handling infinity (∞).

Say you divide a number by infinity. Guess what?

y = 1 / %inf

You get zero.

disp(y)

0.

What if we flip the equation and divide infinity by a number? You've guessed it – infinity!

z = %inf / 2

Infinity makes a comeback in the variable z, represented again as the symbol Inf.

disp(z)

Inf

Just a heads up – some operations with the infinity symbol can veer into the territory of the undefined in mathematics.

Take the operation infinity minus infinity ∞-∞. That's a big no-no – it's indeterminate.

y = %inf - %inf

This time, the symbol Nan, short for Not a Number, pops up in the variable y.

disp(y)

Nan

In simple terms, we've stepped into the realm of the mathematically indeterminate.

The same snag occurs when you attempt to divide infinity by infinity ∞/∞.

y = %inf / %inf

Yet again, our variable y is assigned the symbol Nan.

disp(y)

%nan

So, in conclusion, whenever you dabble with the infinity symbol %inf, bear in mind that it's not just another number – it's a symbol. Depending on the calculation, it could lead to indeterminate or undefined results.

Understanding how and when to use it correctly is vital in your mathematical endeavors.
