I want to show a number in php which has 30 digits after decimal without rounding it up for nano currency, anyone have any Idea?

Question

For example, if I have a number

$x = 340282366920938430000000000000000000000;

I want output as 340282366.92093 and not 340282366.92094 Also for a number like

$y = 23000000000;

I want the output to be 0.000000000000000000023

use string cast an bcdiv

$number = '340282366920938430000000000000000000000';
echo bcdiv($number, '1000000000000000000000000000000', 8);

Return
