Integer part of a quotient
This functionality does not run in MATLAB.
m div n _div(x, m)
x div m represents the integer q satisfying x = q m + r with 0 ≤ r < |m|.
For positive x and m, q = x div m is the integer part of the quotient x/m, i.e., q = trunc(x/m).
x div m is equivalent to the function call _div(x, m).
An integer is returned if both x and m evaluate to integers. A symbolic expression of type "_div" is returned if either x or m does not evaluate to a number. An error is raised if x or m evaluates to a number that is not an integer.
div does not operate on polynomials. Use divide.
With the default setting for mod, the identity (x div m) * m + (x mod m) = x holds for integer numbers x and m:
43 div 13 = trunc(43/13), 43 mod 13 = frac(43/13) * 13
(43 div 13) * 13 + (43 mod 13) = 43
Symbolic expressions of type "_div" are returned, if either x or m does not evaluate to a number:
43 div m, x div 13, x div m
type(x div m)
If x or m are numbers, they must be integer numbers:
1/2 div 2
Error: The argument is invalid. [div]
x div 2.0
Error: The operand is invalid. [_mod]
Integers or symbolic arithmetical expressions; m must not be zero.
