matlab - How can i write a number values in powers of 10? - Stack Overflow
Since e represents to the power 10 and is present in all numbers you listed this is a simple process with many solutions, here is one. % format long is very important otherwise it will appear to you that you have %lost precision. MATLAB hides precision from view to save screen space and to %produce less confusing results to the viewer.

This topic shows how to compute matrix powers and exponentials using a variety of methods. If A is a square matrix and p is a positive integer, then A^p effectively multiplies A by itself p-1 times. For example: A = [1 1 1 1 2 3 1 3 6]; A^2 · ans = 3×3 3 6 10 6 14 25 10 25 46 · If A is square and nonsingular, then A^(-p) effectively multiplies inv(A) by itself p-1 times. A^(-3) ans = 3×3 145.0000 -207.0000 81.0000 -207.0000 298.0000 -117.0000 81.0000 -117.0000 46.0000 · MATLAB® calculates inv(A) and A^(-1) with the same algorithm, so the results are exactly the same.

How can I handle larger powers of 10 like 10^800 in MATLAB? - MATLAB Answers - MATLAB Central
January 28, 2014 - Hi Greg, Thanks for your response, but in my case I have a lengthy polynomial expression (around 10000 terms) in four vairables along with high powers of 10, as I mentioned previously like 1E800. Now I want to process it with continuation method to obtain solution numerically. I tried Mutilprecision Toolbox, but I ended with faliure (since it was not possible to put "mp" before every variable and powers as MATLAB was showing numerous errors regarding parenthesis missing ).

June 22, 2013 - hello, actually what i wanted to know is: if i have a number like 0.6543e+013. Now i just need 0.6543.so i need to divide by 10^the power.but i cant understand how to find this value of power.Is there any function available in matlab that can give me my value...?

I don't really do Matlab, but the usual way to do this in any language I do know is: take the logarithm base 10, then round up that number to the nearest integer, then compute 10 to the power of that number. In Python:
from math import ceil, log
def ceil_power_of_10(n):
exp = log(n, 10)
exp = ceil(exp)
return 10**exp
>>> print(ceil_power_of_10(1024)) # prints 10000
