将两个整数（一个包含整数部分，另一个包含小数部分）组合成一个浮点数 [英] Combine two integers (one containing the integer part, the other the decimal part) into a floating point number

问题描述

如何通过组合两个整数来产生 double 值？我已经试过搜索，但我找不到我正在寻找的答案。

它是这样的：

$ p $ int wholeNumber = 2;
int decimal = 25;


我想做一个 double 到 2.25 。

解决方案

作弊解决方案如下所示：

  string number = wholeNumber +。 +十进制
 double doubleNumber = Double.Parse（number）;清洁的解决方案将涉及检查十进制中有多少个值，除以10 ^的数量并添加它们正如所指出的那样 - 十进制分隔符是文化特定的 - 所以完全正确的版本是
 
 
  string number = wholeNumber + System.Globalization.CultureInfo.CurrentCulture.NumberFormat.NumberDecimalSepar ator + decimal 
 double doubleNumber = Double.Parse（number）; 
  
（我保留了第一个，因为它更容易理解）
How do I produce a double value by combining two integers? I already tried searching but I can't find the answer that I'm looking for. 

It goes like this:
int wholeNumber = 2;
int decimal = 25;
I want to make a double that results into 2.25.
解决方案
Cheating solution goes like this:
string number = wholeNumber + "." + decimal
double doubleNumber = Double.Parse(number);
Clean solution would involve checking how many values you have in the 'decimal', dividing by 10^amount and adding them

As was pointed out - decimal seperator is cultural-specific - so the completly correct version is
string number = wholeNumber + System.Globalization.CultureInfo.CurrentCulture.NumberFormat.NumberDecimalSepar‌​ator + decimal
double doubleNumber = Double.Parse(number);
(I kept the top one because its easier to understand)
