Detailed Description

Functions for converting between integer types and representations.

Function Documentation

di_to_double()

double di_to_double

(

di_int

big

)

Convert integer to double precision floating point.

Parameters

big	Integer to convert (may be NULL)

Returns

Double representation of integer, or 0.0 if big is NULL

Since

1.0.0

Note

May lose precision for very large integers

NULL integers return 0.0

di_to_int32()

bool di_to_int32	(	di_int	big,
		int32_t *	result
	)

Convert integer to 32-bit signed integer.

Parameters

big	Integer to convert (may be NULL)
result	Pointer to store result

Returns

true if conversion successful and no overflow, false otherwise

Since

1.0.0

di_int big = di_from_int32(42);
int32_t value;
if (di_to_int32(big, &value)) {
    printf("Value: %d\n", value);
} else {
    printf("Overflow!\n");
}
di_release(&big);

Definition at line 1378 of file dynamic_int.h.

di_to_int64()

bool di_to_int64	(	di_int	big,
		int64_t *	result
	)

Convert integer to 64-bit signed integer.

Parameters

big	Integer to convert (may be NULL)
result	Pointer to store result

Returns

true if conversion successful and no overflow, false otherwise

Since

1.0.0

Definition at line 1406 of file dynamic_int.h.

di_to_string()

char * di_to_string	(	di_int	big,
		int	base
	)

Convert integer to string representation.

Parameters

big	Integer to convert (may be NULL)
base	Number base (2-36)

Returns

Dynamically allocated string (caller must free), or NULL on failure

Since

1.0.0

di_int big = di_from_int32(-42);
char* str = di_to_string(big, 10);
printf("Value: %s\n", str);  // Value: -42
free(str);
di_release(&big);

Note

Currently only base 10 is implemented

Caller is responsible for freeing returned string

di_to_uint32()

bool di_to_uint32	(	di_int	big,
		uint32_t *	result
	)

Convert integer to 32-bit unsigned integer.

Parameters

big	Integer to convert (may be NULL)
result	Pointer to store result

Returns

true if conversion successful and no overflow/underflow, false otherwise

Since

1.0.0

Definition at line 1437 of file dynamic_int.h.

di_to_uint64()

bool di_to_uint64	(	di_int	big,
		uint64_t *	result
	)

Convert integer to 64-bit unsigned integer.

Parameters

big	Integer to convert (may be NULL)
result	Pointer to store result

Returns

true if conversion successful and no overflow/underflow, false otherwise

Since

1.0.0
