(PA-RISC Systems Only)

DESCRIPTION

This set of calls invokes the library functions for emulating 3000-mode (MPE V/E) packed-decimal opera-

tions. These functions are in library libcl which is searched when the option

-lcl is used with cc or

ld(1).

HPPACADDD() Performs packed-decimal addition.

HPPACCMPD() Compares two packed-decimal numbers.

HPPACCVAD() Converts an ASCII representation to packed-decimal.

HPPACCVBD() Converts a binary representation to packed-decimal.

HPPACCVDA() Converts a packed-decimal number to ASCII.

HPPACCVDB() Converts a packed-decimal number to binary.

HPPACDIVD() Performs packed-decimal division.

HPPACLONGDIVD()

Performs packed-decimal division (alternate routine).

HPPACMPYD() Performs packed-decimal multiplication.

HPPACNSLD() Performs a packed-decimal normalizing left shift.

HPPACSLD() Performs a packed-decimal left shift.

HPPACSRD() Performs a packed-decimal right shift.

HPPACSUBD() Performs packed-decimal subtraction.

For all operations, the value returned in the variable to which the compcode argument points is one of the

following values of type

enum HPPAC_CC:

HPPAC_CCG Result > 0 or operand1 > operand2

HPPAC_CCL Result < 0 or operand1 < operand2

HPPAC_CCE Result == 0 or operand1 == operand2

For all operations, the value returned in the variable to which the pacstatus argument points is one of the

following values of type

enum HPPAC_STATUS. Their meanings are intended to be obvious:

HPPAC_NO_ERROR

HPPAC_DECIMAL_OVERFLOW

HPPAC_INVALID_ASCII_DIGIT

HPPAC_INVALID_PACKED_DECIMAL_DIGIT

HPPAC_INVALID_SOURCE_WORD_COUNT

HPPAC_INVALID_DECIMAL_OPERAND_LENGTH

HPPAC_DECIMAL_DIVIDE_BY_ZERO
