How to read binary float(double) using STL only

ReadBinary.cpp

#include <stdlib.h>
#include <stdio.h>
#include <vector>
#include <string>

    std::string current="your file here";
    std::ifstream infile;
    std::vector<float> n;
    std::vector<std::vector<float>> nums;

    infile.open(current,std::ios::binary | std::ios::in);
    infile.seekg(0,std::ios::end);

    const int length=infile.tellg()/sizeof(float);
    n.resize(length);

    infile.seekg(0,std::ios::beg);
    infile.read(reinterpret_cast<char *>(n.data()),n.size()*sizeof(float));
