C/C++编程笔记:C++中的isunordered函数
所述isunordered()函数定义在 并检查是否第一个参数的值可以有意义与第二个参数进行比较。如果第一个参数不能与第二个参数进行有意义的比较(即一个或两个都是NAN),则返回1,否则返回0。
句法:
bool 掌握MT5交易平台 isunordered(float x,float y);
或者
bool是无序的(double x,double y);
参数:它使用两个值x和y,即用于检查它们是否无序的值。
返回:它返回1,如果x或y值是NAN,否则返回0。
下面的 程序 说明了C ++中的isunordered()函数:
示例一:
#include using namespace std;int main()< float x=6.3; float y=sqrt(-9); cout输出:
x的值是6.3
y的值是= -nan 掌握MT5交易平台
isunordered(x,y)= 1
说明:在示例1中,y的值为NAN,这就是函数返回1的原因。
示例2:
#include using namespace std;int main()< float x=4.6; float y=9.2; cout输出:
x的值是4.6
y的值是9.2
isunordered(x,y)= 0 掌握MT5交易平台
说明:在示例2中,x和y的值不是NAN,这就是函数返回0的原因。

USD Resumes Bullish Momentum After Last Weeks Inflation Data
it seemed quite straightforward that market players went with selling the dollar as yields dropped and risk trades 掌握MT5交易平台 rallied. But the bond 掌握MT5交易平台 market seemed to have other ideas as yields pulled back up and that was causing a bit of a rethink ahead of the weekend.
10-year Treasury yields moved up to contest the 100-day moving average once again as bonds were offered and that saw gains in equities tempered while dollar weakness was also more measured, all things considered.
As yields propped higher, USD/JPY 掌握MT5交易平台 even recovered from a low of 131.73 to trade at around 133.22 at the moment. The high today hit 133.49 and that 掌握MT5交易平台 nearly halves the drop from the US CPI data on Wednesday. Either way, the pair remains caught between key technical levels as outlined before, so nothing much has changed.
But essentially, the bond market is in charge right now. For now, US stocks are on the rise as Treasuries decline, and so are dollar pairs in general. The greenback is a little mixed but it doesn’t look like traders are getting too carried away after the early technical push after the US CPI data. There won’t be much 掌握MT5交易平台 else to influence proceedings before the weekend so the look and feel in the bond market might be the key driver for dollar and risk sentiment in the sessions ahead.
