Yuki,
It is legal to ignore. It is also legal [and free] to learn. 
[I don´t remember if it is easy]
Sympathy for the specialists, sometimes we forget to explain 
[Einstein did it all the time!! He used to disappear from Princeton 
classrooms, he was hiding into some near elementary or preliminary 
school to explain their maths and enjoy with them advanced physics 
together with ice creams]
So,

Boolean  
SYLLABICATION: Bool·e·an  
ADJECTIVE: 
1. Of or relating to a logical combinatorial system treating 
variables, 
such as propositions and computer logic elements, 
through the operators AND, OR, NOT, and XOR: 
a browser that supports Boolean searches.
2. Of or relating to a data type or variable in a programming 
language 
that can have one of two values, true or false.  
ETYMOLOGY: After George Boole. 

Boole, George   
DATES: 1815–1864 
British mathematician and logician who developed a calculus of 
symbolic logic.  

Examples
The 
var1=MACD()>=Signal();
is a boolean variable, it is equal to 1 or 0, as long the relation is 
true or false.[Important note : var1 can not be 1.35 or -264.07, it 
is *always* 1 or 0]
The
var2=dayofweek();
is not Boolean, it may be 0, 1, 2, 3, 4, 5, 6
*but*
the 
var3=dayofweek() == 2
is Boolean, it is true or false and the value of var3 is 1[every 
Tuesday] or 0 [the other days of the week]
You should understand these *strange* things when you deal with T/A 
softwares.
