Please help me to solve this question using Fortran

Q:For example, you need to this which the last bit is 2^-23 = 1.19e-7 for 1 and 2^-23 = 2.38e-7 for 2. Using the Fortran program, I need you to make at least two variables of type (real*4). one of them should be equal to 1.0 and 2.0. Next is using do loop to run it 10 million times. on each variable, you need to add 1.e-7 which is one ten millionth. after finishing the loop, print each variable with a label. (I want you to make some comments on each code.)

Currently I am using JEDIT to write a code.
