If you focus on compute-intensive application, you can increase performance by using the optimized math libraries provided with Sun Performance WorkShop Fortran. The libm math library bundled with the Solaris operating environment contains the functions required by the various standards to which the Solaris software conforms. Some features of the math library are:
Single, double, and quadruple floating-point numeric formats
Algebraic, transcendental, rounding, conversion, and random number functions
Table-driven algorithms for maximum speed and accuracy
