BSON_DECIMAL128_T(3) libbson BSON_DECIMAL128_T(3) BSON Decimal128 Abstraction SYNOPSIS #include <bson/bson.h> #define BSON_DECIMAL128_STRING 43 #define BSON_DECIMAL128_INF "Infinity" #define BSON_DECIMAL128_NAN "NaN" typedef struct { #if BSON_BYTE_ORDER == BSON_LITTLE_ENDIAN uint64_t low; uint64_t high; #elif BSON_BYTE_ORDER == BSON_BIG_ENDIAN uint64_t high; uint64_t low; #endif } bson_decimal128_t; DESCRIPTION The bson_decimal128_t structure represents the IEEE-754 Decimal128 data type. The type bson_decimal128_t is an aggregate that contains two uint64_ts, named high and low. The declaration and layout order between them depends on the endian order of the target platform: low will al- ways correspond to the low-order bits of the Decimal128 object, while high corresponds to the high-order bits. The bson_decimal128_t always has a size of sixteen (16), and can be bit-cast to/from a _Decimal128. EXAMPLE #include <bson/bson.h> #include <stdio.h> int main (int argc, char *argv[]) { char string[BSON_DECIMAL128_STRING]; bson_decimal128_t decimal128; bson_decimal128_from_string ("100.00", &decimal128); bson_decimal128_to_string (&decimal128, string); printf ("Decimal128 value: %s\n", string); return 0; } AUTHOR MongoDB, Inc COPYRIGHT 2009-present, MongoDB, Inc. 1.30.2 Apr 12, 2025 BSON_DECIMAL128_T(3)
