std::isless

STD：：isless

Defined in header ​​
bool isless( float x, float y (1)(since C++11)
bool isless( double x, double y (2)(since C++11)
bool isless( long double x, long double y (3)(since C++11)
bool isless( Arithmetic x, Arithmetic y (4)(since C++11)

1-3%29确定浮点数x小于浮点数。y，而不设置浮点异常。

4%29一组重载或函数模板，用于%281-3%29中未涵盖的所有算术类型参数组合。如果有任何争论积分型，它被铸造成double...

参数

x-floating point value
y-floating point value

返回值

true如果x < y，，，false否则。

注记

内建operator<对于浮点数可能会引发FE_INVALID如果其中一个或两个论点都是NaN。这个函数是一个“安静”的版本。operator<...

另见

lessfunction object implementing x < y (class template)
isgreater (C++11)checks if the first floating-point argument is greater than the second (function)
