1, i = = i + 1A number never equals its own plus 1? Java enforcement requires the use of IEEE 754 floating-point arithmetic operations [IEEE 754], which allows you to represent infinity with a double or float. As we learned in school, Infinity plus 1
5.2 infinity and Nan
IEEE 754 floating point numbers can represent positive or negative infinity, andNan(Not a number ). these three values arise from calculations whose result is undefined or cannot be represented accurately. you can also

NAN and INFINITY in java, javaNANINFINITY
Java floating point operations have two special cases: NAN and INFINITY.
1. INFINITY:
In floating-point calculation, sometimes we encounter a division of 0. How does java solve this problem?
We know that in

The number of bits used to represent the float value in twos complement form
public static final int SIZE = 32;
You only know that the initial value of the set variable is 0. Today, when writing network path analysis, in order to find the closest node from any coordinate, the initial setting is infinitely large, and then constantly replaced until the nearest
Infinity and Nan ProblemsYou want to create or test floating-point numbers with positive infinity, negative infinity, or Nan (not a number).Solution SolutionsPython does not have a special syntax to represent these special floating-point values, but
The following small series for everyone to bring a brief talk about Infinity and Nan in C #. Small series feel very good, now share to everyone, also for everyone to make a reference. Let's take a look at it with a little knitting.
