Description **abs(num)** - absolute value (converts a number to its positive equivalent). \ Example: abs(-256) returns 256 **ceil(num)** - rounds a number up to the nearest integer. \ Example: ceil(25.66) returns 26 **customizable\_round\_division(a,b,count)** - divides two numbers and rounds the result to a specified number of decimal places (count), where a is the dividend and b is the divisor. **customizable\_round\_multiply(a,b,count)** - multiplies two numbers and rounds the result to a specified number of decimal places (count), where a and b are the factors. **exp(num)** - raising Euler’s number e to the power of the parameter.\ Example: exp(2) returns approximately 7.38905609893065 **fac(num)** - factorial of a number (takes one parameter). \ Example: fac(5) returns 120 **floor(num)** - returns the integer part of a number (rounds down). \ Example: floor(25.66) returns 25 **int(num)** - converts a floating-point number to an integer by truncating the decimal part. \ Example: int(1.8) returns 1 **int\_to\_string(number, delimiter)** - converts a number to a string with the specified delimiter. **is\_float(txt)** - checks whether a string is a number (including decimals). **is\_int(txt)** - checks whether a string is a number. \ Example: is\_int("5") returns True, while is\_int("text") returns False **log(num, base)** - calculates the logarithm of a number taking two parameters: the number and the base (default is e).\ Example: log(E) returns 1 (where E is Euler’s number), log(100, 10) returns 2 **max(a, b, c)** - finds the maximum number among the listed values accepting an unlimited number of parameters (each must be a number).\ Example: max(4, 2, 9, 6) returns 9 **md5(text)** - generates an MD5 hash from a string. \ Example: hash = md5("Hello world") returns 3e25960a79dbc69b674cd4ec67a72c62 **min(a, b, c)** - finds the minimum number among the listed values accepting an unlimited number of parameters (each must be a number).\ Example: min(4, 2, 9, 6) returns 2 **pow(num, st)** - raises a number to a power taking two parameters: the base number and the exponent. \ Example: pow(5, 2) returns 25 **pyt(a, b)** - Calculates the square root of the sum of the squares of two values accepting two parameters: a and b. \ Example: pyt(5, 2) returns 5.385164807134504 **random(low, high)** - generates a random number. The function takes two parameters: the lower bound and the upper bound. \ Example: random(-10, 10) **round(num)** - performs mathematical rounding of a number. Example: round(1.8). You can also round to a specific number of decimal places. \ Example: round(1.8888888, 2) returns 1.89. **sha1(text)** - generates a SHA-1 hash from a string. \ Example: hash = sha1("Hello world") returns 7b502c3a1f48c8609ae212cdfb639dee39673f5e **sha256(text)** - generates a SHA-256 hash from a string. \ Example: hash = sha256("Hello world") returns 64ec88ca00b268e5ba1a35678a1b5316d212f4f366b2477232534a8aeca37f3c **sqrt(num)** - calculates the square root of a number taking one parameter: the number. \ Example: sqrt(25) returns 5 **sin() cos() tan() asin() acos() atan() atan2()** - trigonometric functions (remember to consider their domains). {% hint style="success" %} Mathematical functions can be performed not only in the "Calculator" field but also directly in the "Message" field by writing expressions in the following format: **#{2+2}, #{random(0,100)}**, and etc. {% endhint %}
Example Let’s try this function! It’s really simple: just enter it, specify the parameters, and get the result — just like in math!
Here is the result:

## Working with coordinates **distance()**
Description **distance(lat1, lon1, lat2, lon2)**- calculates the distance between two coordinates in kilometers **lat1, lat2** - latitude of the starting and ending points **lon1, lon2** - longitude of the starting and ending points
Examples Example: `distance(52.2296756, 21.0122287, 52.406374, 16.9251681)` Result: `278.5459739738798`
