/ (solidus)
The division operator.
Syntax

a/b

a
is a number, vector, or matrix 
b
is a nonzero number

Description
If a
is a number, vector, or matrix and b
a nonzero number, then a/b
is the mathematical quotient of a
and b
.
If a
is a number, then the type of a/b
is the most specific type possible.
Some examples:

If
a
andb
are both integers, so isa / b
if the quotient is an integer; otherwise,a / b
is a rational number. 
If
a
is an integer andb
a rational number,a / b
is a rational number. 
If
a
is an integer andb
a real number,a / b
is a real number. 
If
a
is an integer andb
a complex number,a / b
is a complex number. 
If
a
is a real number andb
a complex number,a / b
is a complex number. 
If
a
is a rational number andb
a complex number,a / b
is a complex number.
If a
is a vector or matrix, a / b
is complex iff at least one of the operands is complex.
