How to convert amount to float and round correctly in PHP?
To round amounts, use round() in PHP. Let’s say the following are our input values −
$amount=50.78; $quantity=45.5;
Convert them to float like this
$am=(float) round($amount, 4); $quant=(float) round($quantity, 4);
Example
The PHP code is as follows
<!DOCTYPE html> <html> <body> <?php $amount=50.78; $quantity=45.5; $am=(float) round($amount, 4); echo $am,"<br>"; $quant=(float) round($quantity, 4); echo $quant,"<br>"; $correctAmount=round($am*$quant,4); echo "The result is=",$correctAmount; ?> </body> </html>
Output
This will produce the following output
50.78 45.5 The result is=2310.49
