How do I know NMath is correct & accurate?

All NMath libraries have extensive, automated unit test suites for all NMath types and methods. Basic math operations are performed by the native Intel Math Kernel Library (included with NMath). Higher level operations are tested against data from other commercial products and published sources. Each library must pass its associated tests prior to any release, protecting earlier code from being accidentally harmed during revisions. NMath is used and trusted by many industry leading companies.
