Detailed Description

Object used by GnuCash to store all numbers. Always consists of a
numerator and denominator.

The constants GNC_DENOM_AUTO,
GNC_HOW_RND_FLOOR, GNC_HOW_RND_CEIL, GNC_HOW_RND_TRUNC,
GNC_HOW_RND_PROMOTE, GNC_HOW_RND_ROUND_HALF_DOWN,
GNC_HOW_RND_ROUND_HALF_UP, GNC_HOW_RND_ROUND, GNC_HOW_RND_NEVER,
GNC_HOW_DENOM_EXACT, GNC_HOW_DENOM_REDUCE, GNC_HOW_DENOM_LCD,
and GNC_HOW_DENOM_FIXED are available for arithmetic
functions like GncNumeric.add

Look at gnc-numeric.h to see how to use these

Constructor & Destructor Documentation

__init__()

def python.gnucash_core.GncNumeric.__init__	(		self,
			args,
			kargs
	)

Constructor that supports the following formats:
* No arguments defaulting to zero: eg. GncNumeric() == 0/1
* A integer: e.g. GncNumeric(1) == 1/1
* Numerator and denominator intager pair: eg. GncNumeric(1, 2) == 1/2
* A floating point number: e.g. GncNumeric(0.5) == 1/2
* A floating point number with defined conversion: e.g.
  GncNumeric(0.5, GNC_DENOM_AUTO,
    GNC_HOW_DENOM_FIXED | GNC_HOW_RND_NEVER) == 1/2
* A string: e.g. GncNumeric("1/2") == 1/2
