Natural logarithm method not recognised

[Octavio]

Good day dear members of the comp.lang.java.programmer newsgroup.
I've got the following error message while trying to use the "logl()"
method (natural logarithm function) on my NetBeans IDE

symbol : method logl(double)
location: class org.me.mylib.fluidmechanics.DarcyLaw
wfr = 7.08e-3 * ko_dl * depth_dl * (pr_dl - wbp_dl) / (mu_dl *
bo_dl * ((logl(re_dl/rw_dl) - 0.75)));

1 error

Should I import any special mathematic library from NetBeans?

Many thanks.

Octavio

logl()"

I think you meant Math.log()

I think you meant Math.log()

Many thanks to all of you three for your help and answers. Using the
"import java.lang.Math.*;" and Math.log() function there's no more
error message.

But the question remains whether your code is correct. Read Eric’s post
carefully.
