Describe
Give you two big numbers, can you tell the size of their two numbers?
For example, 123456789123456789 to greater than-123456
Input
one row for each set of t
Use the IF statement to determine the size of the two numbers in two ways.The first type:The number of #!/bin/basha=$1b=$2# parameters is not equal to 2 of the case [$#-ne2]{ echo "Usage:$0num1num2" exit NBSP;1} #计算返回值expr $a +0>/dev/nullRETVAL1=$?expr $b +0 >/dev/nullretval2=$? #返回值的结果必须都为0 $? The return value of the previous command 0 indicates a successful test $RETVAL 1-eq 0-a $RETVAL 2-eq0| | {echo "pleaseenterinputtwo" num " again. " NBSP;NBSP;
Mysql date type size comparison --- pull records for a given period of time. In mysql, there are many types of date types, such as date, datetime, and timestamp. Consider this scenario: www.2cto.com pulls the content of a given time period by time period, then we have to use the date type comparison. Table Structure: tablename_tbl + ----------------- + ----------
if (2 > 10){Alert ("Incorrect!");}This comparison will not be the desired result: it is equivalent to 2 >1, and the first bit of 10 is taken out to compare.—————————————————————————————————————————If there is a need to determine whether the current page entered is greater than the total number of pages, if it is greater then the current page is set to the total number of pages.Workaround One:if (eval (pageno) >eval (total)){Pageno=total;}The eval () f

Simple Example of JS date comparison size
This article mainly introduces simple instances with relatively large JS dates. If you need some help, please refer to them.
1. Compare the js Code of date size
The Code is as follows:
2. Js compares the time and date size
The Code is as follows:
Start Time:
End Time:
This class is a class that is precisely calculated in Java1compare objects with equals in general, but BigDecimal is a special one, for example: BigDecimal a=bigdecimal.valueof (1.0); BigDecimal b=bigdecimal.valueof (1.000); In reality these two numbers are equal, but the problem comes A.equals (b) The result is false; why isn't it equal? I don't know the solution to this problem either:if(A.compareto (b) ==0) The result is true Public intCompareTo (BigDecimal val) results are-1less than0equals1
Provides various official and user-released code examples. For code reference, you are welcome to learn how to compare the js time. Generally, the user's front-end compares the selected two time sizes.
// Js time size comparison
Function dateCompare (start_time, end_tile ){
Start_time = start_time.replace (//-/gi ,"/");
End_tile = end_tile.replace (/\-/gi ,"/");
Var time1 = new Date (start_time). getTi

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.

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.
