Dear friends,
I need to code a formula which contains Natural logarithm and "e" power 3 for example. by e I mean the transcendental number which is around 2.71 ... .
Is there any constant in java as "e" or no?
Is there any function that can calculates Ln (natural logarithm)?
do you know any source that can help me?
Thank you so much,
Sahar

And if there wasn't already such a thing, just *type it in* and set it to a variable.
 
I think I'll just lie down here for a second. And ponder this tiny ad:
