1-2) Returns the smaller of the two values.
3-4) Returns the smallest of the values in initializer list ilist.
The (1,3) versions use Template:cpp to compare the values, the (2,4) versions use the given comparison function comp.
Contents |
Parameters
| a, b | - | the values to compare |
| ilist | - | initializer list with the values to compare |
| cmp | - | comparison function object (i.e. an object that satisfies the requirements of Compare) which returns true if if a is less than b.The signature of the comparison function should be equivalent to the following: bool cmp(const Type1& a, const Type2& b); While the signature does not need to have const&, the function must not modify the objects passed to it and must be able to accept all values of type (possibly const) |
Return value
1-2) The smaller of a and b.
3-4) The smallest value in ilist.
Complexity
1-2) Template:complex constant
