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)
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.
