模板参数

RealType-The result type generated by the generator. The effect is undefined if this is not one of float, double, or long double.

成员类型

Member typeDefinition
result_typeRealType
param_typethe type of the parameter set, see RandomNumberDistribution.

成员函数

(constructor)constructs new distribution (public member function)
resetresets the internal state of the distribution (public member function)

世代

运算符%28%29在分布%28公共成员函数%29中生成下一个随机数。

特征

AB返回分布参数%28公共成员函数%29

Param获取或设置分布参数对象%28公共成员函数%29

min返回最小潜在生成值%28公共成员函数%29

MAX返回最大潜在生成值%28公共成员函数%29

非会员职能

operator==operator!=compares two distribution objects (function)
operator<<operator>>performs stream input and output on pseudo-random number distribution (function template)
