Overview
There are 6 types of standard numerical data, namely double, float, int, short, uchar and bool, as shown in the table below.
Name

8 
about +2.0e+308 (16 significant digits) 
float 
single precision floating point
data 
4

int 
signed integer number

2147483648 to 2147483649 
short 
signed short integer 
2 
32767 to 32768 
uchar 
unsigned char 
1 
0  255 
bool 
boolean

0 1 
Function
Numerical data type has no class function. Each data type name itself is in fact a global function, for example:
>a = int() >b = short(19.2) 
a is an integer variable, having a
value of "0" b is a short integer variable, having a value of "19" 
Casting
Casting between each type of numerical data is fully provided in Noobeed. In an operator expression, casting is done in such away that the original data type gets a higher level of precision as much as the highest precision data type in the expression being evaluated. In a function expression, casting is done on arguments of a function to make the data type of the arguments the same data type as what are declared in the function protocol.
Example:
>a = int(8.1) >a 8 >b = sin(a) 
the number 8.1 is converted to 8
variable a is converted to double precision, because the argument of function "sin" requires a double precision number.
