This is the most complete distribution package of the function library (but not the most up-to-date one). It includes these sections-- double: all functions in 64-bit double precision; single: all available functions in 32-bit single precision; long double: all available functions in 80-bit extended precision; 128bit: all available functions in 128-bit long double precision; qlib: all functions in q-type extended (44 to 106 decimal) precision, includes a C++ class for the binary floating point arithmetic and a q-type calculator program; c9x-complex: new C language standard C9X data type for complex variables, header complex.h for GNU C and functions in float complex, double complex, and long double complex precisions.
