A general purpose programming language and compiler
The Gilda language is intended to make it easier and to build high quality software. This is achieved by addressing issues with portability, reuse, ease of use, software maintenance, reliability, testing, and debugging. The language integrates several innovations with a clean and simple syntax.

64 Bit Primality Test
These primality tests extend Steve Worley's 32 bit primality test. They improve on Jim Sinclair's test that uses 7 SPRP tests. 32 bit numbers are checked with a single SPRP test, two are used for 49 bit numbers, and three for 64 bit numbers.
Numbers under 2^32 can be tested using the SPRP bases in: is.prime.32.base.data
Numbers from 2^32 to 2^64 can be tested using the base pairs in: is.prime.64.base.data
The is.prime.gg
Gilda function determines if any 64 bit number is prime.
The list.is.prime.32.g
program lists the bases used to test 32 bit numbers for primality.
It uses this sprp.gg implementation
of the Strong Probable Prime test.
The tests have been independently verified, however, you should verify them before using them. Please let me know if you do.
