Show the whole number

Question

Hi,
I display the line using these

struct nameval
{
    char fld_nm[30];
    float fld_val;
};
nameval binrec;

int main()
{
    std::vector<nameval> records;
    ...
        out1 << binrec.fld_nm << '\t' << setw(10)
            << binrec.fld_val << endl;
        ...

while this is the float shown there in the output line
7.19597e+006

how to exactly show the whole number there?

Many Thanks & Best Regards, Hua Min

What do you mean with "whole number"?

Do you want

7195970 displayed instead of 7.19597e+006?

If this was your question this amy help:

struct nameval
{
    char fld_nm[30];
    float fld_val;
};
nameval binrec;

int main()
{
    std::vector<nameval> records;
    ...
        out1 << binrec.fld_nm << '\t' << setw(10)
            << binrec.fld_val << endl;
        ...

while this is the float shown there in the output line
7.19597e+006

Perhaps you want this:

out1 << binrec.fld_nm << '\t' << setw(10)
     << fixed << binrec.fld_val << endl;

Many thanks all.
Wayne,
I now get this
719597.000000

by this line

        out1 << binrec.fld_nm << '\t' << setw(10)
            << fixed << binrec.fld_val << endl;

how to adjust the decimal numbers there?

Answer 4

        out1 << binrec.fld_nm << '\t' << setw(10)
            << fixed << binrec.fld_val << endl;

how to adjust the decimal numbers there?

Examples:

out1 << binrec.fld_nm << '\t' << setw(10) 
     << setprecision(2)
     << fixed << binrec.fld_val << endl;

out1 << binrec.fld_nm << '\t' << setw(10) 
     << setprecision(0)
     << fixed << binrec.fld_val << endl;
