What does const double eps= 1e-6 mean in C language, and fabs(x & gt；; What does =eps) mean?

constant

Used to define a constant in C++, 1e-6 means 1 multiplied by the sixth power of 10.

You should be FABS (x)

Wafer factory (x & gt=eps)

Wafer factory (double

answer

Is to find the absolute value of floating-point decimal, and shaping is abs(int

I guess you are looking for the solution of an equation now.

X is the difference between two numbers, right?

The meaning of this sentence is

Define a constant

EPS = 0.00000 1；

//Then traverse a set and bring in an equation to get a number A..

Then let a and a known constant.

B, do something.

a-b = x；

fabs(x)& lt； =esp

When the number a is very close to the known constant, it means that you have got it.
