# Comparison

## `eq`
```
(eq value &rest values)
```
`eq` returns t if all `values` are equal to `value`, or nil if any are
not.

For two values to be equal according to `eq`, they must have the same
type. In all cases **except strings**, `eq` compares the immediate value
as returned by [`addr-of`](stdlib_misc.md#addr-of). However, `eq` will
return t for strings with identical contents, **regardless of their
addresses**. To check if two strings reference the same location in
memory, compare their `addr-of`.

## `=`
```
(= value &rest values)
```
`=` compares its arguments numerically. If they are all equal, it
returns `value`, otherwise it returns nil. If any argument is not an int
or float, `=` returns nil.

## `<`
```
(< value &rest values)
```
`<` compares its arguments numerically. If the sequence is monotonically
increasing, it returns the last argument, otherwise it returns nil. If
any argument is not an int or float, `<` returns nil.

## `>`
```
(> value &rest values)
```
`>` compares its arguments numerically. If the sequence is monotonically
decreasing, it returns the last argument, otherwise it returns nil. If
any argument is not an int or float, `>` returns nil.

## `<=`
```
(<= value &rest values)
```
`<=` compares its arguments numerically. If the sequence is
monotonically nondecreasing, it returns the last argument, otherwise it
returns nil. If any argument is not an int or float, `<=` returns nil.

## `>=`
```
(>= value &rest values)
```
`>=` compares its arguments numerically. If the sequence is
monotonically nonincreasing, it returns the last argument, otherwise it
returns nil. If any argument is not an int or float, `>=` returns nil.
