# minimum(_:_:)

Returns the lesser of the two given values.

## Declaration

```swift
static func minimum(_ x: Self, _ y: Self) -> Self
```

## Parameters

- `x`: A floating-point value.
- `y`: Another floating-point value.

## Return Value

Return Value The minimum of x and y, or whichever is a number if the other is NaN.

## Discussion

Discussion This method returns the minimum of two values, preserving order and eliminating NaN when possible. For two values x and y, the result of minimum(x, y) is x if x <= y, y if y < x, or whichever of x or y is a number if the other is a quiet NaN. If both x and y are NaN, or either x or y is a signaling NaN, the result is NaN. Double.minimum(10.0, -25.0) // -25.0 Double.minimum(10.0, .nan) // 10.0 Double.minimum(.nan, -25.0) // -25.0 Double.minimum(.nan, .nan) // nan The minimum method implements the minNum operation defined by the IEEE 754 specification.
