But my answer below takes that into account.

Try this:
a = 4.5236e+15
b = a / 10^floor(log10(a))
fprintf('b = %g\n', b)

It works well ! Thanks to Image Analyst. But for negative numbers, it gives complex number as output.
For eg:-
a = -4.5236e+15
b = a / 10^floor(log10(abs(a)))
fprintf('b = %g\n', b)
Output:
b =
3.0227 + 3.3655i
b = 3.02274
a = -4.5236e+15
b = a / 10^floor(log10(abs(a)))
fprintf('b = %g\n', b)
Output:
b =
-4.5237
b = -4.5237
@Ajin R. Not sure what you meant, but the output is not what you said it was. Look:
% First code snippet:
a = -4.5236e+15;
b = a / 10^floor(log10(abs(a)))
fprintf('b = %g\n', b)
% Second code snippet:
a = -4.5236e+15;
b = a / 10^floor(log10(abs(a)))
fprintf('b = %g\n', b)
