Constructor & Destructor Documentation

Decimal	(	DecimalMantissa	mantissa = 0,
		DecimalExponent	exponent = 0
	)

Initializes instance from compound components.

Decimal ( int  )

explicit

Decimal ( Double  value )

explicit

Converts from Double value using default conversion precision.

Decimal	(	Double	value,

	)

Converts Double value to decimal.

Parameters

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

Decimal

(
