BSON_DECIMAL128_FROM_STRING_W_LEN(3)

SYNOPSIS

bool
bson_decimal128_from_string_w_len (const char *string,


                                   int len,


                                   bson_decimal128_t *dec);

PARAMETERS

string: A string containing ASCII encoded Decimal128.
len: The length of string in bytes, or -1 meaning the string is null-terminated.
dec: A bson_decimal128_t <>.

DESCRIPTION

Parses the string containing ascii encoded Decimal128 and initialize the bytes in dec. See the Decimal128 specification <https://github.com/mongodb/specifications/blob/master/source/bson-decimal128/decimal128.md> for the exact string format.

RETURNS

Returns true if valid Decimal128 string was provided, otherwise false and dec will be set to NaN.

EXAMPLE

bson_decimal128_t dec;
bson_decimal128_from_string_w_len ("1.00", 4, &dec);
bson_decimal128_from_string_w_len ("1.00", -1, &dec);
