All said programmers lazy, life is not lazy, such as shampoo, wash face, of course, also includes sharing. Here's a look at the pie chart I've drawn with H5 's new label canvas, which is randomly generated, generates 6 of equal numbers dynamically, and I do random data generation,With the text, each share of the proportion on the display and opinions. , which is very good for analyzing data. The picture is as follows;Canvas is a label provided by HTML

The decode function can replace the results of a query, and decode actually function like an if statement.Decode (VAR,VAR1,VALUE1,VAR2,VALUE2,VAR3,VALUE3) is equivalent to if Var=var1 then ... else if Var=var2 then ... else var=var3 then ...But only if it is equal to the situation, if the judgment is greater than less than the case, such as if a>b, the only use of decode is not possible, you need to add the sign () function.The function of the sign fu
The main object of the study of advanced algebra is the linear space, the $\mathbb{f}$ of all the times less than or equal to $n-1$ in the number domain constitute a linear space, recorded as $v=\mathbb{f}[x]_{n}$, then obviously $\dim v=n$, and it is easy to know that there is a set of bases for $$1,x,x^{2},\dots,x^{n-1}$$In fact, according to the definition of linear space base it is easy to verify that there are also base $$1, (X-a), (x-a) ^{2},\do
, the rest of the bit is zero, this number and x corresponding bit XOR.Example: x=10101110, make x low 4 bits flip, with x ^ 0000 1111 = 1010 0001 can be obtained.(2) differ from 0 or, retain the original value, X ^ 0000 0000 = 1010 1110.This can be clearly seen from the example above.Take the inverse operator (~)To participate in the operation of a data, press bits for "negation" operation.Operational rules: ~1=0; ~0=1;that is: to a binary number in the reverse position, the 0 will change to 0.
Let us consider sets of positive integers less than or equal to N. Note, all elements of a set is different. Also Note that the order of elements doesnt matter, which is, both {3, 5, 9} and {5, 9, 3} mean the same set.Specifying the number of SET elements and their sum to be k and S, respectively, sets satisfying the conditions is Limite D. When n = 9, k = 3 and S =, {6, 8, 9} are the only such set. There may is more than one such set, in general, how

}
The comparison between "0e0983" and "0e0473" will also be equal, which is why?
Reply to discussion (solution)
You have a very special formula, you have to use a surrogate type of comparison.if ("0e1683" = = = "0e0473")The reason is this:PHP automatically converts data types when compared, making the data types on both sides of an expression consistent. Th
The table has a lot of data, but a few are strange, the field is float type, 2 values are the same
Payment value =299.7
Feiyong value =299.7

At this point can still query out, and just a few have this problem, the others are normal
