The values to select the minimum from. At least two arguments must be passed, and they must be comparable with <.
The minimum of the passed-in values. The type of the returned value is the type among the passed arguments that is able to store the smallest value. If at least one of the arguments is NaN, the result is an unspecified value. See std.algorithm.searching.minElement for examples on how to cope with NaNs.
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); ulong f = 0xffff_ffff_ffff; const uint g = min(f, 0xffff_0000); assert(g == 0xffff_0000); dchar h = 100; uint i = 101; static assert(is(typeof(min(h, i)) == dchar)); static assert(is(typeof(min(i, h)) == uint)); assert(min(h, i) == 100);
With arguments of mixed signedness, the return type is the one that can store the lowest values.
int 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);
Iterates the passed arguments and returns the minimum value.
