While writing some code to ensure user input is valid I came across an issue with std::numeric_limits<T>::min(); where T is a floating point type i.e double/float etc. Using -std::numeric_limits<double>::max(); allows me to get the real minimum value but you would expect...

cvsba库http://www.uco.es/investiga/grupos/ava/node/39,不知道怎么回事,记得以前编译没有错误,不知道作者是否更新了还是怎么着,新的现在有以下错误: 解决方法: 打开源码,找到 cvsba.h(在src文件夹),在cvsba.h里添加include<limits>,再编译就okay了。没想到库里会缺头文件,真是醉了。
std::numeric_limits<T>::lowest From cppreference.com <cpp |types |numeric limits Returns the lowest finite value representable by the numeric typeT, that is, a finite valuexsuch that there is no other finite valueywherey<x. This is different fromstd::numeric_limits<T>::min()for...
Defined in header <limits> template< class T > class numeric_limits; The std::numeric_limits class template provides a standardized way to query various properties of arithmetic types (e.g. the largest possible value for type int is std::numeric_limits<int>::max()). This information ...
