BloombergLP::bdldfp

Namespace for decimal floating‐point types and utilities.

Types

Name

Description

DecimalConvertUtil

This struct provides a namespace for utility functions that convert between the decimal floating‐point types of bdldfp_decimal and various other formats.

DecimalConvertUtil_IntelDfp

This struct provides a namespace for utility functions that convert between the decimal floating‐point types of bdldfp_decimal and various other formats.

DecimalFormatConfig

This attribute class characterizes how to configure certain behavior of bdldfp::DecimalUtil::format functions.

DecimalImpUtil

This struct provides a namespace for utility functions that implement core decimal floating‐poing operations.

DecimalImpUtil_IntelDfp

This struct provides a namespace for implementation functions that work in terms of the underlying C‐style decimal floating point implementation, Intel's DFP library.

DecimalNumGet

A facet type (mechanism) used in reading decimal floating‐point types. Note that this type does not follow BDE conventions because its content is dictated by the C++ standard and native standard library implementations. See ISO/IEC TR 24733 3.10.2 for details.

DecimalNumPut

A facet type (mechanism) used in writing decimal floating‐point types. Note that this type does not follow BDE conventions because its content is dictated by the C++ standard and native standard library implementations. See ISO/IEC TR 24733 3.10.3 for details.

DecimalNumPut_WideBufferWrapper

This class provides a wrapper around a buffer of the specified (template parameter) CHARTYPE. CHARTYPE shall be either plain character type char or wide character type wchar_t. The width of wchar_t is compiler‐specific and can be as small as 8 bits. The template parameter WCHAR_8_BITS shall be true if wchar_t and char widths are the same, i.e. 8 bits, and false otherwise. This class provides accessors to the beginning and the end of the buffer of CHARTYPE characters.

DecimalStorage

This struct provides a namespace for types for storing Binary Integral Decimal representation of a decimal floating point value.

DecimalUtil

This utility struct provides a namespace for functions using the decimal floating point types defined in the bdldfp_decimal package.

DecimalUtil_CStringUtil

This component‐private utility struct provides a namespace for the flatten overload set intended to be used in concert with an overload set consisting of a function template with a deduced argument and an non‐template overload accepting a const char *. The actual implementation of the functionality would be in the const char * overload whereas the purpose of the function template is to invoke the `const char *` overload with a null‐terminated string.

Decimal_BslFmtFormatterImpl

This class template provides the implementation for all possible decimal floating point formatting styles and the parsing of the format specification. The specified t_VALUE template type argument determines the type of decimal floating point value use, while the specified t_CHAR determines both the formatting string and the output's character type. The behavior is undefined unless t_VALUE is one of Decimal32, `Decimal64, or Decimal128, and `t_CHAR is on of char or `wchar_t`.

Decimal_FormatterSpecification

This template is the implementation of the bsl::format specification for bdldfp::Decimal* types. It parses as well as postprocesses format specifications for bdldfp::Decimal* type formatted arguments, as well as stores the results of that pasring: the specification.

Decimal_StandardNamespaceCanary

An empty class used for error detection when looking for the original name of the standard namespace. Do not use it.

Decimal_Type128

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.

Decimal_Type32

These are the actual (decimal floating‐point) types being implemented. They use a different name to cause an error if the official types are forward declared: The exact definition of the decimal types is left unspecified so that that can potentially be aliases for built‐in types.

Decimal_Type64

This value‐semantic class implements the IEEE‐754 64 bit decimal floating‐point format arithmetic type. This class is a standard layout type that is const thread‐safe and exception‐neutral.

Uint128

This value‐semantic type represents a 128‐bit integer, with host machine byte order.

faux_numeric_limits

This class is used as a base‐class for manifest constants in the std::numeric_limits specializations to overcome a Sun compiler issue.
