# DEFDBL
## Effect
Defines a variable or a range of variables as double precision.
As an alternative, a single variable can be declared as double precision by appending the `#` sign to its name.
## Syntax
`DEFDBL <StartVariable>-<EndVariable>,<StartVariable>-<EndVariable>...`
_Note: Parameters can not end with a comma or hyphen alone._
## Parameters
`<StartVariable>` and `<EndVariable>` are letters put in alphabetic order. If `<EndVariable>` is not specified, all the variables beginning with the specified letter will be defined as double precision.
## Example
```basic
10 DEFDBL A-Z
20 A=7/6
30 PRINT "7 divided by 6 (in double precision) is ";A
RUN
7 divided by 6 (in double precision) is 1.1666666666667
```
