<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> |
