YAML real field type object

A real field type object is the type of floating point number data fields, found in data streams.

Properties

Name Type Description Req? Default

Name	Type	Description	Req?	Default
`class`	String	This property’s value must be `real`.	Yes if the `$inherit` property is not set.
`$inherit`	String	Name of a field type alias from which to inherit.	Yes if the `class` property is not set.
`size`	Positive integer	Size of this field type’s instances (bits). This property’s value must be one of: 32 Single-precision floating point number instances (binary32). 64 Double-precision floating point number instances (binary64).	Yes
`alignment`	Power-of-two integer	Alignment of the first bit of this field type’s instances within a CTF packet (bits).	No	8

class

String

This property’s value must be real.

Yes if the $inherit property is not set.

$inherit

String

Name of a field type alias from which to inherit.

Yes if the class property is not set.

size

Positive integer

Size of this field type’s instances (bits).

This property’s value must be one of:

Yes

alignment

Power-of-two integer

Alignment of the first bit of this field type’s instances within a CTF packet (bits).

Depending on the value of the size property:

Example 1. Basic single-precision real field type object.

class: real
size: 32

Example 2. Basic double-precision real field type object.

class: real
size: 64

Example 3. 64-bit-aligned single-precision real field type object.

class: real
size: 32
alignment: 64
