Detailed Description

Float primitive element.

This element stores an IEEE floating-point number. 4-byte and 8-byte floats are allowed.

Constructor & Destructor Documentation

tide::FloatElement::FloatElement	(	uint32_t	id,
		double	value,
		EBMLFloatPrec	precision = `EBML_FLOAT_PREC_DOUBLE`
	)

Create a new float element with no default.

Parameters:

[in]	id	The element's ID, as an unsigned integer up to 28 bits.
[in]	value	The element's value.
[in]	precision	The element's precision, single or double. This only has an effect when writing the float to file.

tide::FloatElement::FloatElement	(	uint32_t	id,
		double	value,
		double	default_value,
		EBMLFloatPrec	precision = `EBML_FLOAT_PREC_DOUBLE`
	)

Create a new float element with a default value.

Parameters:

[in]	id	The element's ID, as an unsigned integer up to 28 bits.
[in]	value	The element's value.
[in]	precision	The element's precision, single or double. This only has an effect when writing the float to a file.
[in]	default_value	The default value of the element.

Member Function Documentation

virtual std::streamsize tide::FloatElement::body_size ( ) const [protected, virtual]

Get the size of the body of this element.

Implements tide::Element.

virtual FloatElement& tide::FloatElement::operator= ( double const & rhs ) [virtual]

Value assignment operator.

Reimplemented from tide::PrimitiveElement< double >.

virtual EBMLFloatPrec tide::FloatElement::precision ( ) const [inline, virtual]

Get the precision setting.

Definition at line 83 of file float_element.h.

virtual void tide::FloatElement::precision ( EBMLFloatPrec precision ) [inline, virtual]

Set the precision setting.

This value determines if the float is single or double precision. The precision value has no effect until the float is written to a file, at which point single-precision floats are written using 4 bytes while double-precision floats are written using 8 bytes.
