What best practices should be followed when passing float values as arguments to PHP math functions like asin()?

When passing float values as arguments to PHP math functions like `asin()`, it is important to ensure that the values are within the valid range for the function. For `asin()`, the input value should be between -1 and 1 to avoid errors or unexpected results. To handle this, you can use the `min()` and `max()` functions to clamp the input value within the valid range before passing it to the math function.

// Ensure the input value is within the valid range for asin()
$input = min(max($input, -1), 1);

// Calculate the arcsine of the clamped input value
$result = asin($input);
