nan 0

At work we are constantly writing code, writing JavaScript, very little time for conceptual research. I have nothing to do today, I studied the relationship between "null" and "0". I hope you have seen the end of the harvest. Alert (null>=0) What

  Zero divided by zero = Nan, that is, 0/0 = Nan An infinite number of non-zero values divided by zero, that is, 5.0/0 = infinity,-5.0/0 =-infinity Nan participates in the operation of Nan, that is Nan + Nan = Nan, Nan-nan = Nan, Nan * Nan = Nan,

When the game is running, code that is unsafe to write is prone to Nan exceptions. Once Nan appears the entire game does not collapse also necrosis, the game is to be directly beat back the rhythm, is a development and testing personnel each have to

This paper summarizes the meaning, generation and judging methods of Nan and INF in C language. Nan in the C language means not a number, which is equivalent to #IND: indeterminate (Windows) generates:An undefined operation was performed on a

1. Misunderstanding correction of attribute NanNan (not a number) defines a non-numeric special value in the list of numbers, and it has an object that does not have the value of any non-numeric type equal to Nan, only if the arithmetic operation

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

Strictly judge NaN in JavaScript, while javascript judges nan I also encountered this question on FreeCodeCamp: Delete all values in the array. In JavaScript, the false values include false, null, 0, "", undefined, and NaN. For NaN judgment, JS

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

1.NaNIn JavaScript, Nan represents "not a number". This value is returned primarily when parsing a string error: Copy Code code as follows: > Number ("xyz") Nannan The name is "not a number", but it can also be said not to
