Maxinum length of a float

[ttpparker]

Im trying to work out a "power to" equation (x to the power of y). I am using the following while loop.

 

while($counter < $TermDays)

{

$Daily2Worker = $Daily2Worker * $TermDays;

$counter = $counter + 1;

}

 

This runs 1500 times, the script executes fine but when I output the value $Daily2Worker I get "NaN". If i reduce the number of times the loop runs it works fine. Can anyone help or suggest an alternative way of performing a to the power of calculation.

Why not just use the pow() function?

Knowing how you initialise the values of $Daily2Worker and $TermDays might also help identify what your specific issue is with what should be a very simple loop

 

 

Also, your logic will not give you x to the power of y
