<dt>ln(x)</dt>
|
|
<dd>This function calculates the natural logarithm of x,<br>e.g. ln(123)=4.812...</dd>
|
|
|
|
<dt>log(x; base)</dt>
|
|
<dd>This function calculates the logarithm of x with a base equal 'base'<br>
|
|
It's using the formula: log(x; base) = ln(x) / ln(base)<br>

log(123; 4)=3.471...</dd>

|
|
<dt>exp(x)</dt>
|
|
<dd>This function calculates the exponential function of x<br>exp(20)=e^20=485165195.409...</dd>
