inspect()

public

Returns debugging information about the value as a string of comma-separated values in angle brackets with a leading #:

BigDecimal.new(“1234.5678”).inspect -> “#<BigDecimal:b7ea1130,‘0.12345678E4’,8(12)>”

The first part is the address, the second is the value as a string, and the final part ss(mm) is the current number of significant digits and the maximum number of significant digits, respectively.

{
    ENTER(5);
    Real *vp;
    volatile VALUE obj;
    unsigned int nc;
    char *psz, *tmp;

    GUARD_OBJ(vp,GetVpValue(self,1));
    nc = VpNumOfChars(vp,"E");
    nc +=(nc + 9) / 10;

    obj = rb_str_new(0, nc+256);
    psz = RSTRING_PTR(obj);
    sprintf(psz,"#<BigDecimal:%lx,'",self);
    tmp = psz + strlen(psz);
    VpToString(vp, tmp, 10, 0);
    tmp += strlen(tmp);
    sprintf(tmp,"',%lu(%lu)>",VpPrec(vp)*VpBaseFig(),VpMaxPrec(vp)*VpBaseFig());
