The Float data type
The data type of floating point numbers is Float. By default, Float matches floating point numbers
within the limitations of Ruby's Float class. Practically
speaking, this means a 64-bit double precision floating point value. You can use parameters to
restrict which values Float matches.
Parameters
The full signature for Float is:
Float[<MIN VALUE>, <MAX VALUE>]These parameters are optional. They must be listed in order; if you need to specify a later parameter, you must also specify values for any prior ones.
| Position | Parameter | Data type | Default | Description |
|---|---|---|---|---|
| 1 | Minimum value | Float | negative infinity | The minimum value for the float. This parameter accepts the special
value default, which uses its
default value. |
| 2 | Maximum value | Float | infinity | The maximum value for the float. This parameter accepts the special
value default, which uses its
default value. |
Examples:
FloatMatches any floating point number.
Float[1.6]Matches any floating point number greater than or equal to 1.6.
Float[1.6, 3.501]Matches any floating point number from 1.6 to 3.501, inclusive.
