This value‐semantic class implements the IEEE‐754 128 bit decimal floating‐point format arithmetic type. This class is a standard layout type that is const thread‐safe and exception‐neutral.

Constructors

bdexStreamIn

Assign to this object the value read from the specified input stream using the specified version format, and return a reference to stream. If stream is initially invalid, this operation has no effect. If version is not supported, this object is unaltered and stream is invalidated, but otherwise unmodified. If version is supported but stream becomes invalid during this operation, this object has an undefined, but valid, state. Note that no version is read from stream. See the bslx package‐level documentation for more information on BDEX streaming of value‐semantic types and containers.

bdexStreamOut

Write the value of this object, using the specified version format, to the specified output stream, and return a reference to stream. If stream is initially invalid, this operation has no effect. If version is not supported, stream is invalidated, but otherwise unmodified. Note that version is not written to stream. See the bslx package‐level documentation for more information on BDEX streaming of value‐semantic types and containers.

operator*=

Multiplication assignment operators

operator++

Add 1.0 to the value of this object and return a reference to it. Note that this is a floating‐point value so this operation may not change the value of this object at all (if the value is large) or it may just set it to 1.0 (if the original value is small).

operator+=

Addition assignment operators

operator‐‐

Add ‐1.0 to the value of this object and return a reference to it. Note that this is a floating‐point value so this operation may not change the value of this object at all (if the value is large) or it may just set it to ‐1.0 (if the original value is small).

operator‐=

Subtraction assignment operators

operator/=

Division assignment operators

value

Return the value of the underlying implementation.

operator BloombergLP::bslmf::NestedTraitDeclaration<Decimal_Type128, is_trivially_copyable>

Declare the specified nested trait for this decimal type.
