# int function is used to transfer double var into int var
# the normal type of number in balloon script is double
var int=func(value)

# num function is used to translate a string into a number
var num=func(value)

};

# size function is used to count the number of members in an array
var size=func(value)

# rand function is used to make random float numbers between 0 and 1 ([0,1))
# written by C: srand(unsigned(time(NULL))) rand()
