Each entry-point name in Table B-1 is unique and corresponds to data-type specific calculations in a CPML routine. For example, the acos function has five entry-point-names for the OpenVMS Alpha operating system. Because five floating-point data types are available, five acos routines are provided: math$acos_s, math$acos_t, math$acos_f, math$acos_g, and math$acos_x. Use the entry-point name that corresponds to your input argument data type.
