read numbers from files in columns, one column whole numbers, other column numbers with decimals

Any of those help The best way would be to get each separately. If it is from a file then you can do this:
int itemnum;
double price;

inputFile >> itemNum >> price; //If the columns are ItemNumber then Price
inputFile >> price >> itemnum; //If the columns are the other way around
#include <fstream>
#include <iostream>

int main()
{
    int input1;
    double input2;

    //Open file
    std::ifstream inFile;
    inFile.open("myFile.txt"); //or whatever the file name is

    while(!inFile.eof())
    {
        //Get input
        inFile >> input1 >> input2;

        //Print input
        std::cout << input1 << " " << input2 << " ";
    }

    //Close file
    inFile.close();

    return 0;
}

will help you I want to perform a simple calculation on each number in a column of whitespace delimited data using Bash utilities such as cut and bc. The data may look like something such as the following: , try this short line:
awk '$2=$2" "sprintf("%.3f",$2)' file
kent$  echo "string 0.998663 string string string
string 0.998592 string string string
string 0.999096 string string string"|awk '$2=$2" "sprintf("%.3f",$2)'
string 0.998663 0.999 string string string
string 0.998592 0.999 string string string
string 0.999096 0.999 string string string

Column A numbers matched with Column B numbers that are assigned to Column C =column D?

seems to work fine It is hard to guess what your data looks like, so assuming your data looks as below:

}
FNR != NR {

around this issue Have you thought about using the seq.POSIXt function in R's base library?
The function takes the following: seq.POSIXt(from, to, by, length.out = NULL, along.with = NULL, ...)
library(data.table)
fromDate <- as.POSIXct('2018-03-22')
toDate <- as.POSIXct('2018-03-23')

df<-as.data.table(seq.POSIXt(fromDate, toDate, by = '3 min'))
