# Simple Values
|
|
|
|
|
|
Racket values include numbers, booleans, strings, and byte strings. In
|
|
|
DrRacket and documentation examples \(when you read the documentation in
|
|
|
color\), value expressions are shown in green.
|
|
|
|
|
|
_Numbers_ are written in the usual way, including fractions and
|
|
|
imaginary numbers:

```racket
|
|
|
1 3.14
|
|
|
1/2 6.02e+23
|
|
|
1+2i 9999999999999999999999
|
|
|
```
|
|
|
|
|
|
_Booleans_ are `#t` for true and `#f` for false. In conditionals,
|
|
|
however, all non-`#f` values are treated as true.
|
|
|
|
|
|
> +\[missing\] \(later in this guide\) explains more about booleans.
|
|
|
|
|
|
_Strings_ are written between doublequotes. Within a string, backslash
|
|
|
is an escaping character; for example, a backslash followed by a
|
|
|
doublequote includes a literal doublequote in the string. Except for an
|
|
|
unescaped doublequote or backslash, any Unicode character can appear in
|
|
|
a string constant.

```racket
|
|
|
"Hello, world!"
|
|
|
"Benjamin \"Bugsy\" Siegel"
|
|
|
"λx:(μα.α→α).xx"
|
|
|
```
|
|
|
|
|
|
When a constant is evaluated in the REPL, it typically prints the same
|
|
|
as its input syntax. In some cases, the printed form is a normalized
|
|
|
version of the input syntax. In documentation and in DrRacket’s REPL,
|
|
|
results are printed in blue instead of green to highlight the difference
|
|
|
between an input expression and a printed result.
