numbers

I've searched for it but i can't find a conclusive answer to my question... I need to know what is the storage size of a number(p) field in Oracle. Examples: NUMBER(1), NUMBER(3), NUMBER(8), NUMBER(10) etc... The storage used depends on the actual numeric value, as well as the column precision and scale of the column. The Oracle 11gR2 concepts guide says : Oracle Database stores numeric data in variable-length format. Each value is stored in scientific notation, with 1 byte used to store the exponent. The database uses up to 20 bytes to store the mantissa, which is the part of a floating-point

How can I call myNumbers() java function in Jenkinsfile? Or do I need to have a separate groovy script file and that file I should place inside java jar which has Test class? My Jenkinsfile: def numToEcho = [1,2,3,4] def stepsForParallel = [:] for (int i = 0; i < numToEcho.size(); i++) { def s = numToEcho.get(i) def stepName = "echoing ${s}" stepsForParallel[stepName] = transformIntoStep(s) } parallel

I'm trying to understand how the sequence numbers of the TCP header are generated. In some places I read that it is the "index of the first byte in the packet" ( link here ), on some other sites it is a random 32bit generated number that is then incremented. I don't really know which is which, so here are some questions: How is the initial sequence number generated? (Please provide an RFC number if there is one) How is it incremented? How is the secret key generated? I read some of the RFCs like RFC 6528 , RFC 793 , and RFC 1948 but I can't seem to understand which one is actually implemented.

I need to work with decimals. In my program, the user need to put a number with decimals to convert that number. The problem is: If I try to convert the argument into a number I get a integer without decimals. # ARGV[0] is: 44.33 size = ARGV[0] puts size.to_i # size is: 44 # :( You call to_i , you get integer. Try calling to_f , you should get a float. For more string conversion methods, look here . If you want more accurate answer with the calculation to avoid bug like this https://www.codecademy.com/en/forum_questions/50fe886f68fc44056f00626c you can use conversion to decimal example :

题目描述 从扑克牌中随机抽5张牌，判断是不是一个顺子，即这5张牌是不是连续的。2~10位数字本身，A为1，J为11，Q为12，K为13，而大王，小王可以看成任意数字。为了方便我们将大小王看成0。 思路： 1.找出5张牌中得大小王，即0的个数 2.将牌排序，找出相邻牌中的空隙数 3.如果空缺的总数小于或等于0的个数，那么数组是连续的。 在下面的代码中，使用了sort函数，第一个参数为数组首地址，第二个参数为数组尾地址，第三个参数为排序规则。默认为升序 我的代码： bool IsContinuous( vector< int > numbers ) { int len = numbers.size(); if (len< 5 ) return false ; sort(numbers.begin(),numbers.end()); int ZeroNum = 0 ; int GapNum = 0 ; for ( int i = 0 ; i < len;i++ ) { if (numbers[i] == 0 ) ZeroNum ++ ; } int x = ZeroNum; for ( int j = ZeroNum+ 1 ; j < len;j++ ) { if (numbers[j] == numbers[x]) return false ; GapNum += numbers[j]
