Detailed Description

Decimal type for better precision.

Constructor & Destructor Documentation

Decimal ( )

inline

Default constructor.

Initializes the decimal value to zero.

Decimal	(	DecimalMantissa	mantissa,
		DecimalExponent	exponent
	)

Initializes instance from compound components.

Decimal ( SInt32  value )

explicit

Initializes instance with zero exponent.

Decimal ( Double  value )

explicit

Converts from Double value using default conversion precision.

Decimal	(	Double	value,
		size_t	precision
	)

Converts Double value to decimal.

Parameters

value	double precision floating-point value.
precision	defines conversion precision.

Decimal

(

const Decimal &

other

)

Initializes as copy of given value.
