div

division, rounds down to near-

est integer

byte, short, word, integer, 

longint, longword

byte, short, word, inte-

ger, longint, longword

mod

modulus, returns the remain-

be used with floating points)

byte, short, word, inte-

ger, longint, longword

Division by Zero

If 0 (zero) is used explicitly as the second operand (i.e. 

x div 0

), the compiler will report an error and will not gener-

ate code. 

But in case of implicit division by zero: 

x div y

, where 

y

 is 0 (zero), the result will be the maximum integer (i.e 

255

, 

if the result is 

byte

 type; 

65536

, if the result is 

word

 type, etc.).

Unary Arithmetic Operators

Operator 

-

 can be used as a prefix unary operator to change sign of a signed value. Unary prefix operator 

+

 can be 

used, but it doesn’t affect data.

For example:

b = -a
