Message:


I know this is basic questing but I am unable to convert the value.
Example :
I need roundup values like 0.09 to 9


.09 = 9
.01 = 1
.5 = 50

I am trying this


number_format((float)0.09, 3, '.', '')

output is 0.090


How does Excel convert 0.0988325 into 9.88%?

My Answer:
In PHP, you can use the `round()` function to round up decimal values. Here is an example of how you can achieve this:

php
$value = 0.09;
$roundedValue = round($value * 100);
echo $roundedValue; // Output: 9


This code will multiply the decimal value by 100 to convert it to a percentage, then round it up using the `round()` function.

As for Excel converting 0.0988325 into 9.88%, Excel is likely displaying the value as a percentage with two decimal places. To achieve this in PHP, you can modify the code as follows:

php
$value = 0.0988325;
$roundedValue = round($value * 100, 2);
echo $roundedValue; // Output: 9.88


This code will round the decimal value to two decimal places and then multiply it by 100 to convert it to a percentage.
