<h1>Arithmetic functions</h1>
<p><strong>Note:</strong> If a function takes more than one argument, the arguments are separated with semicolon ';'.</p>
<h2>Other functions</h2>
<dl>
<dt>sqrt(x)</dt>
<dd>Sqrt returns the square root of x<br>sqrt(9)=3</dd>
<dt>root(x ; n)</dt>
<dd>The nth root of a 'x', 'n' must be integer and not negative, if 'n' is zero the result is one,
if 'x' is zero the result is zero and we assume that the root(0;0) is not defined, e.g.<br>
root(8;3)=2<br>
root(-8;3)=-2
</dd>
<dt>factorial(n)</dt>
<dd>The factorial function<br>factorial(6)=1*2*3*4*5*6=720</dd>
<dt>gamma(x)</dt>
<dd>The gamma function<br>gamma(45.89)=7,861174...e+55</dd>
<dt>abs(x)</dt>
<dd>The absolute value of x<br>abs(-10)=10</dd>
<dt>sgn(x)</dt>
<dd>This function returns the sign of x that means when the x is positive the result is 1, when the x is negative
the result is -1 and when the x is zero the result is zero too<br>
sgn(-10)=-1<br>
sgn(0)=0<br>
sgn(5)=1</dd>
<dt>mod(x ; y)</dt>
<dd>Mod returns the remainder from the division x by y<br>mod(10; 2.2)=1.2 because 10=2.2*4 + 1.2</dd>
<dt>max(x1; x2; ...)</dt>
<dd>This functions takes any number of arguments. It returns the max value of them. If there are not any arguments
the function returns the max value which can be held in this precision.<br>
max(2;5;8;3)=8<br>
max()=6.97846825730330952352039893e+646457021 (assuming the small precision is selected)</dd>
<dt>min(x1; x2; ...)</dt>
<dd>This functions takes any number of arguments. It returns the min value of them. If there are not any arguments
the function returns the min value which can be held in this precision.<br>
min(45;-23;18;19)=-23<br>
min()=-6.97846825730330952352039893e+646457021 (assuming the small precision is selected)
</dd>
<dt>sum(x1; x2; ...)</dt>
<dd>This functions takes one or more arguments. It returns the sum of them.<br>
sum(4;2;9;3)=18
</dd>
<dt>avg(x1; x2; ...)</dt>
<dd>This functions takes one or more arguments. It returns the arithmetic mean. (The sum divided by
the number of arguments)<br>
avg(4;2;9;3)=4.5
</dd>
