Last Modified: 2012-05-11
Hi all

I have a mathematical method in java
that returns the following value = 1.1638387640158259E-107
How can I convert this number to double
eg..  0.000000000

Thanks in advance..

See code below for example method
varRaidus  = Function.calcRadioActiveRadius(t, startRadius, rateOfDecay);
gives 1.1638387640158259E-107
Which I cannot do any thing with.. 
expected 0.000000000
