struct Point
{
	double x, y;
}

import std.algorithm : min, max;

auto min_x = double.max;
auto max_x = -double.max;
auto min_y = double.max;
auto max_y = -double.max;

foreach (const ref p; points) // fold
{
	min_x = min(min_x, p.x);
	max_x = max(max_x, p.x);
	min_y = min(min_y, p.y);
	max_y = max(max_y, p.y);
}

Hello,

I am trying to find the min and max values from an array of points, I want to replace this with the std.algorithm fold, but I can't quite figure out the syntax for doing it?

i got this working

 points.fold!(
     (a, b) => min(a, b.x), (a, b) => max(a, b.x),
     (a, b) => min(a, b.y), (a, b) => max(a, b.y)
 )(double.max,  -double.max, double.max,  -double.max));
