Detailed Description

IDL 128-bit floating-point type.

This type is used by DDS to represent the IDL long double type and can be used among platforms for which there isn't a standard definition for a 128-bit floating-point type.

LongDouble can be converted to and from decimal, but this doesn't ensure interoperability with C, C++ or other applications for which a long double can have different representations. If a distributed system uses different long double representations, the applications are responsible for manually interpreting the individual bytes (provided as Int0 to Int3).

Constructor & Destructor Documentation

LongDouble() [1/4]

LongDouble

(

int[]

ints

)

Creates a LongDouble from its 32 bytes, as 4 ints

LongDouble() [2/4]

LongDouble

(

decimal

value

)

Creates a LongDouble from a decimal

LongDouble() [3/4]

LongDouble

(

double

value

)

Creates a LongDouble from a double

LongDouble() [4/4]

LongDouble

(

int

value

)

Member Function Documentation

CompareTo()

int CompareTo

(

LongDouble

other

)

Compares the result of converting ToDecimal().

Equals()

bool Equals

(

LongDouble

other

)

Compares with another LongDouble

GetBits()

int [] GetBits

(

)

Gets the bits in an array of 4 integers

operator decimal()

static operator decimal ( LongDouble  value )

explicitstatic

Converts from LongDouble to decimal

Note that the encoding of this LongDouble is not guaranteed to be compatible with a .NET decimal type.

operator LongDouble()

static operator LongDouble ( decimal  value )

explicitstatic

Converts from decimal to LongDouble

ToDecimal()

decimal ToDecimal

(

)

Converts from LongDouble to decimal

Note that the encoding of this LongDouble is not guaranteed to be compatible with a .NET decimal type.

ToString()

override string ToString

(

)

Returns ToDecimal().ToString().
