The number from consists * of two consecutive signed integers. The first is the coefficient, with * its implied decimal point at the low-order end. The second is the * exponent as a power of 10. * * * gets DIS_SUCCESS if everything works well. It gets an error * code otherwise. In case of an error, the character pointer is * reset, making it possible to retry with some other conversion strategy. * * By fiat of the author, neither loss of significance nor underflow are * errors. */ #include /* the master config generated by configure */ #include #include #include #include #include "dis.h" #include "dis_.h" /* to work around a problem in a compiler */ #if SIZEOF_LONG_DOUBLE == SIZEOF_DOUBLE #ifdef LDBL_MAX #undef LDBL_MAX #endif /* LDBL_MAX */ #define LDBL_MAX DBL_MAX #endif /* SIZEOF_LONG_DOUBLE == SIZEOF_DOUBLE */ #if defined(__GNUC__) && defined(__DBL_MAX__) #ifdef LDBL_MAX #undef LDBL_MAX #endif /* LDBL_MAX */ #define LDBL_MAX __DBL_MAX__ #ifdef HUGE_VAL #undef HUGE_VAL #endif #define HUGE_VAL LDBL_MAX #endif dis_long_double_t disrl( int stream, int *retval) { int expon; unsigned uexpon; int locret; int negate; unsigned ndigs; unsigned nskips; dis_long_double_t ldval; assert(retval != NULL); assert(disr_commit != NULL); ldval = 0.0L; locret = disrl_(stream, &ldval, &ndigs, &nskips, LDBL_DIG, 1); if (locret == DIS_SUCCESS) { locret = disrsi_(stream, &negate, &uexpon, 1); if (locret == DIS_SUCCESS) { expon = negate ? nskips - uexpon : nskips + uexpon; if (expon + (int)ndigs > LDBL_MAX_10_EXP) { if (expon + (int)ndigs > LDBL_MAX_10_EXP + 1) { ldval = ldval < 0.0L ? -HUGE_VAL : HUGE_VAL; locret = DIS_OVERFLOW; } else { ldval *= disp10l_(expon - 1); if (ldval > LDBL_MAX / 10.0L) { ldval = ldval < 0.0L ? -HUGE_VAL : HUGE_VAL; locret = DIS_OVERFLOW; } else ldval *= 10.0L; } } else { if (expon < LDBL_MIN_10_EXP) { ldval *= disp10l_(expon + (int)ndigs); ldval /= disp10l_((int)ndigs); } else ldval *= disp10l_(expon); } } } if ((*disr_commit)(stream, locret == DIS_SUCCESS) < 0) locret = DIS_NOCOMMIT; *retval = locret; return(ldval); }
