Does STL have a BigInt class implementation? (numbers with many digits held into a container)
915
The BIGINT data type is a machine-independent method for representing numbers in the range of -2 63-1 to 2 63-1. ESQL/C provides routines that facilitate the conversion from the BIGINT data type to other data types in the C language. The BIGINT data type is internally represented with the ifx_int8_t structure.
They are typically implemented as arrays or simpler types (for example integers). Operations are then performed on this representation. Since you can put a lot of numbers in an array, you can represent very large integers.
Constructor taking a long (64 bit) base-10 number as parameter. Constructor accepting a variable-length string, containing base-10 digits. Constructor using a byte array parameter, for converting raw binary data into a BigInteger , at the ratio 2 raw bytes to 1 BigInteger digit.
The C++ standard library (sometimes erroneously referred to as "STL") does not contain any extended precision support.

No, but MPIR/GMP have C++ interfaces.
