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 "dis.h" #include "dis_.h" #undef disrf static unsigned ndigs; static unsigned nskips; static double dval; static int disrd_( int stream, unsigned int count) { int c; int negate; unsigned int unum; char *cp; char scratch[DIS_BUFSIZ+1]; if (dis_umaxd == 0) disiui_(); memset(scratch, 0, DIS_BUFSIZ+1); c = (*dis_getc)(stream); switch (c) { case '-': case '+': negate = (c == '-'); nskips = (count > FLT_DIG) ? count - FLT_DIG : 0; count -= nskips; ndigs = count; dval = 0.0; do { c = (*dis_getc)(stream); if ((c < '0') || (c > '9')) { if (c < 0) { return (DIS_EOD); } return(DIS_NONDIGIT); } dval = dval * 10.0 + (double)(c - '0'); } while (--count); count = nskips; if (count > 0) { count--; switch ((*dis_getc)(stream)) { case '5': if (count == 0) break; /* fall through */ case '6': case '7': case '8': case '9': dval += 1.0; /* fall through */ case '0': case '1': case '2': case '3': case '4': if ((count > 0) && ((*disr_skip)(stream, (size_t)count) < 0)) { return(DIS_EOD); } break; default: return(DIS_NONDIGIT); /*NOTREACHED*/ break; } } dval = negate ? -dval : dval; return(DIS_SUCCESS); /*NOTREACHED*/ break; case '0': return(DIS_LEADZRO); break; case '1': case '2': case '3': case '4': case '5': case '6': case '7': case '8': case '9': unum = c - '0'; if (count > 1) { if ((*dis_gets)(stream, scratch + 1, count - 1) != (int)count - 1) { return(DIS_EOD); } cp = scratch; if (count >= dis_umaxd) { if (count > dis_umaxd) break; *cp = c; if (memcmp(scratch, dis_umax, dis_umaxd) > 0) break; } while (--count) { c = *++cp; if ((c < '0') || (c > '9')) { return(DIS_NONDIGIT); } unum = unum * 10 + (unsigned)(c - '0'); } } return(disrd_(stream, unum)); /*NOTREACHED*/ break; case - 1: return(DIS_EOD); /*NOTREACHED*/ break; case -2: return(DIS_EOF); /*NOTREACHED*/ break; default: return(DIS_NONDIGIT); /*NOTREACHED*/ break; } /* END switch(c) */ dval = HUGE_VAL; return(DIS_OVERFLOW); } /* END disrd_() */ float disrf( int stream, int *retval) { int expon; unsigned uexpon; int locret; int negate; assert(retval != NULL); assert(stream >= 0); assert(dis_getc != NULL); assert(dis_gets != NULL); assert(disr_skip != NULL); assert(disr_commit != NULL); dval = 0.0; if ((locret = disrd_(stream, 1)) == DIS_SUCCESS) { locret = disrsi_(stream, &negate, &uexpon, 1); if (locret == DIS_SUCCESS) { expon = negate ? nskips - uexpon : nskips + uexpon; if (expon + (int)ndigs > FLT_MAX_10_EXP) { if (expon + (int)ndigs > FLT_MAX_10_EXP + 1) { dval = dval < 0.0 ? -HUGE_VAL : HUGE_VAL; locret = DIS_OVERFLOW; } else { dval *= disp10d_(expon - 1); if (dval > FLT_MAX / 10.0) { dval = dval < 0.0 ? -HUGE_VAL : HUGE_VAL; locret = DIS_OVERFLOW; } else dval *= 10.0; } } else { if (expon < DBL_MIN_10_EXP) { dval *= disp10d_(expon + (int)ndigs); dval /= disp10d_((int)ndigs); } else dval *= disp10d_(expon); } } } if ((*disr_commit)(stream, locret == DIS_SUCCESS) < 0) locret = DIS_NOCOMMIT; *retval = locret; return (dval); }
