Questions tagged [infinity]

Infinity is a specific floating point value that is always larger than any other floating point value. It may arise as a result of division by zero, arithmetic overflow and other exceptional operations. Infinity is different from the maximal still valid floating point value that the certain data type can hold. IEEE 754 floating point standard allows both positive and negative infinity values.

Infinity is a specific floating point value that is always larger than any other floating point value. It may arise as a result of division by zero, arithmetic overflow and other exceptional operations. IEEE 754 floating point standard allows both positive and negative infinity values.

Infinity is different from the maximal still valid floating point value that the certain data type can hold. This value is still smaller than the infinity.

Some programming languages allow to specify the infinity in the code explicitly. For instance, the Java code

    double [] values = ...
    double min = Double.POSITIVE_INFINITY;

    for (double x: values) 
      if (x < min) min = x;

can be used to obtain the minimal value in the array that only contains usual, valid floating point values.

Why is infinity's floating point representation apparently 0^n?

I am trying to understand floating point representations. I do not understand the 'infinity' 'NaN' representations in floating point. I am looking at the table provided by TopCoder. Infinity is represented by an exponent of all 1s and a Mantissa of…

how to represent integer infinity in python 3?

I have a variable with type annotation as int. I want to assign it an arbitrary large value as default. If it was a float, I could have used math.inf. However, what should I use if variable is integer? def calc(x: int = math.inf): ...

Why infinity to power 0 is implemented to be 1?

This is an undeterminate form in Math, but in Python and JavaScript it results in 1. Tested in Python: inf=float('inf') print(inf**0) JavaScript console.log(Math.pow(Infinity,0)) console.log(Infinity**0)

Planck's function in Fortran 90

I have the following formula for a function in Fortran 90 used to find the spectral radiance at a given wavelength and temperature. I've expressed it as: intensity = (2.0d0*h*nu**(3.0d0))/c**(2.0d0) * 1d0 / (EXP((h*nu)/(k*T))-1d0) Where I take…

Use class object as another type

It's difficult to explain. I've created a Infinity Class, Infinity< t > , for example Infinity < int >, and it contains a bool that says if the infinity is + or - and operators overloading, so you can do all of this: infinity + int, int - infinity,…

Can I use Infinity and -Infinity as an initial value for Max and Min variables?

I thought that it would be acceptable to initialize my Max value to -Infinity but this did not turn out to be the case in JavaScript. If Infinity is considered a number type why can't I use it in my comparisons? var windowStart =0, sum =0, max =…
