h1. Operators in Scol

h2. On integers :

plus : + : 1+2  5 + 20

minus : - : 1 - 2  20 - 5

multiply : * : 1*2  20 * 5

divide : / : 1/2  20 / 5

modulo : mod : mod 1 2  mod 20 5

h2. On floatting points :

plus : +. : 1.0 +.2.2  5.1 +. 20.0

minus : -. : 1.0 -. 2.2  20.0 -. 5.1

multiply : @*.@ : 1.0*.2.2  20.0 *. 5.1

divide : /. : 1.0/.2.2  20.0 /. 5.1

modulo : mod. : 

h2. On strings :

concatenate : strcat : strcat "Bob" "Alice" => "BobAlice"

concatenate : strncat : strncat "Bob" :: " and " :: "Alice" :: nil => "Bob and Alice"

sub string : substr aString position length : substr "Bob and Alice are married" 8 5 => "Alice" 

h2. Logicals :

and : && : (x > 5) && (x < 10)

or : || : (x < 5) || (x > 10)

not : ! : !1 (=> 0)

h2. Bit by bit  (like C) :

and : & : 5 & 3   5 & 2

or : | : 5 | 3   5 | 2

@>> : 5 >> 1@

@<< : 5 << 1

@

h2. Compare :

@> : 5 > 2 is true@

@>= : 5 >= 5 is true@

@< : 5 < 2 is false@

@<= : 5 <= 2 is false@

@== : 5 == 5 is true@

h2. Others :

different != : 5 != 2 is true

compare two strings : strcmp stringA stringB : return 1, -1 or 0 if equal (like C)

h2. Priority :

like C
