In PHP, what is the difference between using bcscale() and number_format() for handling float values?

When dealing with float values in PHP, bcscale() is used to set the scale for all BCMath functions, which affects the precision of mathematical operations. On the other hand, number_format() is used to format a number with grouped thousands and a specified number of decimal places for display purposes. If you need to control the precision of calculations, use bcscale(). If you need to format a number for display, use number_format(). 

// Using bcscale() to set the scale for precision in mathematical operations
bcscale(2); // Set the scale to 2 decimal places
$sum = bcadd('1.234', '2.345'); // $sum will be '3.58'

// Using number_format() to format a number for display
$number = 1234.56789;
$formattedNumber = number_format($number, 2); // $formattedNumber will be '1,234.57'
