Reoccuring Number

[SirChick]

I have a script which goes something like this:

 

user in puts a number lets say 2.

 

This multiplied by 5 to make 10.

 

Then a sum of two float format numbers are added together.. this equals = $totalpercentage

 

In the user's details i got "total" and what happens is i got a sum that does:

 

10 * 1 + $totalpercentage/100

this is then added on to the "total"

 

But now out of completely rare chances i hit a situation which created a result of:

 

1 Self Defence Sessions giving you a defence gain of 4.99999999999E-5.

 

I'm assuming that means its a reoccuring result...is there a way i can round off the value to 4.99999999999 when ever such a reoccuring result appears?

I don't know if you can round it to 4.9999... But you could use a simple round() function to round it to 5.
