In this + * mode, most floating point constants are given as arrays + * of octal integers to eliminate decimal to binary conversion + * errors that might be introduced by the compiler. + * + * For little-endian computers, such as IBM PC, that follow the + * IEEE Standard for Binary Floating Point Arithmetic (ANSI/IEEE + * Std 754-1985), the symbol IBMPC should be defined. These + * numbers have 53-bit significands. In this mode, constants + * are provided as arrays of hexadecimal 16 bit integers. + * + * Big-endian IEEE format is denoted MIEEE. On some RISC + * systems such as Sun SPARC, double precision constants + * must be stored on 8-byte address boundaries. Since integer + * arrays may be aligned differently, the MIEEE configuration + * may fail on such machines. + * + * To accommodate other types of computer arithmetic, all + * constants are also provided in a normal decimal radix + * which one can hope are correctly converted to a suitable + * format by the available C language compiler. To invoke + * this mode, define the symbol UNK. + * + * An important difference among these modes is a predefined + * set of machine arithmetic constants for each. The numbers + * MACHEP (the machine roundoff error), MAXNUM (largest number + * represented), and several other parameters are preset by + * the configuration symbol. Check the file const.c to + * ensure that these values are correct for your computer. + * + * Configurations NANS, INFINITIES, MINUSZERO, and DENORMAL + * may fail on many systems. Verify that they are supposed + * to work on your computer. + */ + +/* +Cephes Math Library Release 2.3: June, 1995 +Copyright 1984, 1987, 1989, 1995 by Stephen L.
