DecimalFormat is a concrete subclass of NumberFormat that formats decimal numbers.
Definition: decimfmt.h:669
C++ API: Unicode String.
U_EXPORT UBool operator==(const StringPiece &x, const StringPiece &y)
Global operator == for StringPiece.
void * UClassID
UClassID is used to identify classes without using the compiler's RTTI.

virtual UClassID getDynamicClassID() const
ICU4C "poor man's RTTI", returns a UClassID for the actual ICU class.
#define U_NAMESPACE_END

Definition: uversion.h:132
UErrorCode
Error code to replace exception handling, so that the code is compatible with all C++ compilers...
Definition: utypes.h:396
This class represents the information needed by DecimalFormat to format currency plural, such as "3.00 US dollars" or "1.00 US dollar".
