I know about php's built in round() function, which return 2 for 1.6. But it return 1 for 1.1. I want to return the next number if the given number has a fractional part. For example, I want to return 2 for 1.1, or 1.01, or even 1.0001. But I don't want to return the same for 1.0, which may return 1 itself. How can I achieve this in PHP?
Take a look at php's ceil().
echo ceil(4.3); // 5
echo ceil(9.999); // 10
echo ceil(-3.14); // -3
Use ceil() to round up to the next number
echo ceil(1.0); // will echo 1
