I am trying to establish the delta I need when doing float comparison in PHP. I want to take a closer look at my variables to see the difference.I have 2 computed variables, $a, $b.\[code\]$a = some_function();$b = some_other_function();\[/code\]How can I see the exact number which PHP uses? I want to compare them with this formula, where I need to specify the delta:\[code\]$delta = 0.00001;if (abs($a-$b) < $delta) { echo "identical";}\[/code\]var_dump($a, $b) returns 1.6215; 1.6215. but I know that they are not exactly equal because\[code\]var_dump($a === $b);\[/code\]evaluates to false;Why doesn't \[code\]var_dump()\[/code\] print the internal value?
