Detailed Description

Functions for comparing arbitrary precision integers.

Function Documentation

◆ di_compare()

int di_compare	(	di_int	a,
		di_int	b
	)

Compare two integers.

Parameters

a	First integer (may be NULL)
b	Second integer (may be NULL)

Returns: -1 if a < b, 0 if a == b, 1 if a > b

Since: 1.0.0

Note: NULL values are treated as zero for comparison

Definition at line 1305 of file dynamic_int.h.

◆ di_eq()

bool di_eq	(	di_int	a,
		di_int	b
	)

Test if two integers are equal.

Parameters

a	First integer (may be NULL)
b	Second integer (may be NULL)

Returns: true if a == b, false otherwise

Since: 1.0.0

Definition at line 1333 of file dynamic_int.h.

◆ di_ge()

bool di_ge	(	di_int	a,
		di_int	b
	)

Test if first integer is greater than or equal to second.

Parameters

a	First integer (may be NULL)
b	Second integer (may be NULL)

Returns: true if a >= b, false otherwise

Since: 1.0.0

Definition at line 1349 of file dynamic_int.h.

◆ di_gt()

bool di_gt	(	di_int	a,
		di_int	b
	)

Test if first integer is greater than second.

Parameters

a	First integer (may be NULL)
b	Second integer (may be NULL)

Returns: true if a > b, false otherwise

Since: 1.0.0

Definition at line 1345 of file dynamic_int.h.

◆ di_is_negative()

bool di_is_negative ( di_int big )

Test if integer is negative.

Parameters

big	Integer to test (may be NULL)

Returns: true if integer is negative, false otherwise

Since: 1.0.0

Note: NULL is considered zero (not negative)

Definition at line 1358 of file dynamic_int.h.

◆ di_is_one()

bool di_is_one ( di_int big )

Test if integer equals one.

Parameters

big	Integer to test (may be NULL)

Returns: true if integer equals 1, false otherwise

Since: 1.1.0

Note: NULL is considered zero (not one)

Definition at line 1368 of file dynamic_int.h.

◆ di_is_positive()

bool di_is_positive ( di_int big )

Test if integer is positive (> 0)

Parameters

big	Integer to test (may be NULL)

Returns: true if integer is positive, false otherwise

Since: 1.0.0

Note: NULL is considered zero (not positive)

Definition at line 1363 of file dynamic_int.h.

◆ di_is_zero()

bool di_is_zero ( di_int big )

Test if integer is zero.

Parameters

big	Integer to test (may be NULL)

Returns: true if integer is zero, false otherwise

Since: 1.0.0

Note: NULL is considered zero

Definition at line 1353 of file dynamic_int.h.

◆ di_le()

bool di_le	(	di_int	a,
		di_int	b
	)

Test if first integer is less than or equal to second.

Parameters

a	First integer (may be NULL)
b	Second integer (may be NULL)

Returns: true if a <= b, false otherwise

Since: 1.0.0

Definition at line 1341 of file dynamic_int.h.

◆ di_lt()

bool di_lt	(	di_int	a,
		di_int	b
	)

Test if first integer is less than second.

Parameters

a	First integer (may be NULL)
b	Second integer (may be NULL)

Returns: true if a < b, false otherwise

Since: 1.0.0
