Data Fields
uint32_t	length
	The number of words in the magnitude, with no leading zero words.
bool	negative
	Whether or not the integer is negative.
union {
uint32_t   value [2]
	The words of an integer whose length is at most 2. More...
uint32_t *   values
	The words of an integer whose length is greater than 2.
}	words
	The words of the magnitude.

Detailed Description

A structure represents an arbitrary-sized integer.

The magnitude is stored as 32-bit words, least significant first.

Field Documentation

length

uint32_t pm_integer_t::length

The number of words in the magnitude, with no leading zero words.

Zero has no words, so a zeroed pm_integer_t is always positive zero.

value

uint32_t pm_integer_t::value[2]

The words of an integer whose length is at most 2.

Words past the length are zero.

[union]

union { ... } pm_integer_t::words

The words of the magnitude.

Read them through pm_integer_words or pm_integer_uint64_value rather than directly.
