[Baypiggies] scientific notation: string to int

[Bryce Verdier]

So I've been given a project for work, a large CSV file with many many 
numbers and such to parse through. The lines that look like this:

b1021384-6633-4756-b3e1-c36d34c1dfd2, clientname_001,Thu Dec  2 00:00:00 
UTC 2010,2.96116E+11,0,0, Thu Dec  2 00:00:00 UTC 2010,577078067
20,15228831373,80966857300,

so I'm curious if there is a way to turn the string of scientific notion 
into the actual numerical value?

All ideas are welcomed and thank in advance,

Bryce
