js & float number bug 前端最好不要处理任何的 float number 的计算/精确度转换的操作,不热很容易丢失精度,显示错误! 前端显示个 0.0 都很费劲,最好的方式就是数值型的数据后端全部给字符串 labelWeight = 0; if(labelWeight === 0) { labelWeight = labelWeight + `.0`; } else { if (!labelWeight) { labelWeight = ""; } } &q…

Find next higher number with same digits. Example 1 : if num = 25468, o/p = 25486 Example 2 : if num = 21765, o/p = 25167 Example 3 : If num = 54321, o/p = 54321 (cause it's not possible to gen a higher num than tiz with given digits ). Google的面试题,实际…

float,double,number都是oracle的数值类型.1个汉子=2个英文=2个字节float表示单精度浮点数在机内占4个字节,用32位二进制描述. double表示双精度浮点数在机内占8个字节,用64位二进制描述. 1.只有一个参数时,如NUMBER(24).表示所定义的数字最大可设置24位整数.2.有两个参数时,如NUMBER(38, 3).表示所定义的数字最大是38位长,其中包含3位小数.就是说这个类型最大可设置35位整数和3位小数.…

There is no float type. Looks like you want float64. You could also use float32 if you only need a single-precision floating point value. package main import "fmt" func main() { i := 5 f := float64(i) fmt.Printf("f is %f\n", f) }…

[题目] 输入数字n,按顺序输出从1最大的n位10进制数.比如输入3,则输出1.2.3一直到最大的3位数即999. [分析] 这是一道很有意思的题目.看起来很简单,其实里面却有不少的玄机. [常规思路] 应聘者在解决这个问题的时候,最容易想到的方法是先求出最大的n位数是什么,然后用一个循环从1开始逐个输出.很快,我们就能写出如下代码:  C++ Code  1234567891011121314   // Print numbers from 1 to the maximum number wi…

/*In this problems, we’ll talk about BIG numbers. Yes, I’m sorry, big numbers again…. Let N be a positive integer, we call S=NN the “big big power” of N. In this time, I will calculate the exact value of S for a positive integer N. Then, I tell you S…
