I had dinner with a friend yesterday. He said whether two integer values are equal. Here, the manager also explained the problem of Java integer value comparison. This is a frequent problem during the interview.First, let's look at an example:

performed.
Conversions are performed in the direction of increased data length to ensure that the accuracy is not reduced. such as int and long operation, the int is converted into a long type before the operation.
All floating-point operations are performed in double-precision, even if the expression containing only float single-precision arithmetic is converted into double type and then calculated.
Char and short participate in the operation, you must first convert to int type.
The examples in this article describe a PHP implementation that compares two string date size methods. Share to everyone for your reference. as follows:

A Unix timestamp $date=1255392000 that eventually gets a date.
Many times when doing a search, the search time can not be greater than the current date, the
Descrtion:Please help Xiao Ming Write a Super Fast Function which result was like below:
int cmp (int a, int b, int c){Superlong factorial = 1;for (int i = 1; i Factorial *= i;
Superlong power = 1;for (int i = 1; I Power *= B;
if (Factorial return-1;else if (factorial = = Power)return 0;Elsereturn 1;}
Superlong is a type of an integer with unlimited length.
Input:Input contains multiple test case. One line one case, and each case is three integers, a, B, C.We guarantee that 1
