Function std.algorithm.comparison.min
Iterates the passed arguments and returns the minimum value.
Prototype
MinType!T min(T...)( T args ) if (T.length >= 2);
Parameters
| Name | Description |
|---|---|
| args | The values to select the minimum from. At least two arguments
must be passed, and they must be comparable with <. |
Returns
The minimum of the passed-in values.
Example
int a = 5; short b = 6; double c = 2; auto d = min(a, b); static assert(is(typeof(d) == int)); assert(d == 5); auto e = min(a, b, c); static assert(is(typeof(e) == double)); assert(e == 2); // With arguments of mixed signedness, the return type is the one that can // store the lowest values. a = -10; uint f = 10; static assert(is(typeof(min(a, f)) == int)); assert(min(a, f) == -10); // User-defined types that support comparison with < are supported. import std.datetime; assert(min(Date(2012, 12, 21), Date(1982, 1, 4)) == Date(1982, 1, 4)); assert(min(Date(1982, 1, 4), Date(2012, 12, 21)) == Date(1982, 1, 4)); assert(min(Date(1982, 1, 4), Date.min) == Date.min); assert(min(Date.min, Date(1982, 1, 4)) == Date.min); assert(min(Date(1982, 1, 4), Date.max) == Date(1982, 1, 4)); assert(min(Date.max, Date(1982, 1, 4)) == Date(1982, 1, 4)); assert(min(Date.min, Date.max) == Date.min); assert(min(Date.max, Date.min) == Date.min);
