GreaterThan

介绍​

实现类型GreaterThan<T, U>, 就像T > U一样. 负数不需要考虑.

ts
GreaterThan<2, 1> //should be true
GreaterThan<1, 1> //should be false
GreaterThan<10, 100> //should be false
GreaterThan<111, 11> //should be true
ts
GreaterThan<2, 1> //should be true
GreaterThan<1, 1> //should be false
GreaterThan<10, 100> //should be false
GreaterThan<111, 11> //should be true
