A variable is like a container. We can give the variable a name, use it to store the data, read it, or change it. It is often used in actual programming.
Click the Create variable option, enter the name of the variable, click OK to create
For example: assign the variable initial value A=6, and add the variable 2 after one second.
There are some basic arithmetic blocks in Math, such as "addition, subtraction, multiplication and division".
constant Fill in any number and connect to other objects for assignment
Common operation Add data on both sides of the expression to add, subtract, multiply and divide power
Surplus Add data on both sides of the expression to make the remainder
Special number judgment Add a value to set whether the judgment is true (for example, whether it is odd or even or prime), if it is true, it is True, otherwise it is False.
Array calculation Summing an array, calculating the maximum or minimum, the average, etc.
round Rounding off decimals or going to the bottom
advance operation Find trigonometric functions, absolute values, etc.
convert to int Convert the value to an integer
convert to float Convert values to floating point numbers
Add data to both sides of the expression, assign the expression to a variable or other object, and get the result.
When making games or animations, we sometimes need some random elements, and Random can generate random numbers according to our needs.
random fraction Randomly generate a number between 0 and 1 each time it is executed
random integer Specify a random range, each time it is executed, randomly generate an integer in the range
Set a random range with a constant and assign a random intger to a variable
Map is another variable container model that can store any type of object.
creat map Create key-value pairs of map.
map clear clear key-value.
map contain key Confirm if there is a key in map
get ken in map Get the value of Specified key.
in map add key value Add key-value in map.
in map set key value change the value of key in map.
in map delete key Delete specified key
Add a create map to create a map, add some elements to the map, Specify keywords and values
If the variable is a container, the array is a collection of many containers. We can assign values to any of the variables in the array.
length of Measure the length of the array (ie the number of elements in the array)
X is empty Determine whether an array is empty. When it is established, the expression is True, otherwise it is False.
in list find Array index, indexed positive or reverse specified element
create empty list Add a value to set whether the judgment is true (for example, whether it is odd or even or prime), if it is true, it is True, otherwise it is False.
create list with Customize an array
in list get Get the index value of an index element
in list get sub-list from Set an index to the specified value in the array
icreat list with item repeated times Create an array and use the element to repeat a certain number of times to fill
reverse Array in reverse order
in list set as Set an index to the specified value in the array
make list from text with delimiter Create an array from text, using a separator
Add a create list to create an array, add some elements to the array, call elements iteratively or by using other methods
