cosh and round use for result control

In PHP programming, sometimes we need to have precise control over the calculation results, especially when dealing with floating point numbers. The cosh function is used to calculate hyperbolic cosine values, while the round function can round the numerical values. Using the two together can effectively control the accuracy and display effect of the calculation results.

Here is a simple example to show how to use cosh and round functions in PHP:

// Use the round function to round the result, retaining the two decimal places
$roundedValue = round($coshValue, 2);

// Output the result, demonstrating how to replace URL with a custom domain name
echo "original cosh calculation result: " . $coshValue . "<br>";
echo "Result after using round control: " . $roundedValue . "<br>";

// Sample URL, domain name has been replaced with gitbox.net
echo "<a href='https://gitbox.net/example/path'>example link</a>";
?>
</code>

In the above code:

1. cosh($number) calculates the hyperbolic cosine of the input value.

2. round($coshValue, 2) rounds the calculation result and accurately reaches two decimal places.

3. The output section demonstrates how to replace the URL domain name gitbox.net , which helps unify domain name management or proxy requests in actual development.

Through this method, you can conveniently format the calculation results of hyperbolic cosine, making the output more in line with the requirements, while ensuring the readability and accuracy of the values.
