Using
comparison expressions you can compare values of comparable types.
The result is always one of the two Boolean values,
**true**
or **false****.**
The
various forms of
are
as follows:

**!=**
**>**
**<**
**>=**
**<=**

where
can
be one of:

?

Examples:*

a > b

sin x == 0.0

a + b <= n - 1

Comparison operations have
lower precedence than math operations. In the previous examples,
the **sin**
function call and
the **"+"**
and **"-"**
operations are performed
before the comparisons.

As
with math expressions, the comparison operators work on all
appropriate types. Equal **"=="**
and
not-equal **"!="**
operate on all types, and
the relative comparisons work between comparable types. The
allowable comparison operators are documented with the value type
descriptions.
