Exponential precision of power engineering format

Hello guys! I have the number 143903542.580052, by default matlab prints 1.439035e+08 but I want to print 143.9035e+06, I've tried so many matlab help links but nothing to do. Is there a way?

For Command Window and ‘tooltip’ formatting, use:

format short eng

or:

format long eng

For printed output (using fprintf or sprintf), I wrote a little utility anonymous function for my own use to do that:

engntn = @(x) [x*10.^(-3*floor(log10(abs(x))/3))  3*floor(log10(abs(x))/3)];    % Engineering Notation Mantissa & Exponent
Result2 = sprintf('%.4fE%+04d', engntn(Q1))

for example:

Q1 =
          143903542.580052

Result2 =
    '143.9035E+006'

Thank you, I hope Matlab implement some function like yours in the future.

My FEX submission num2eng will do this for printed output. It handles edge cases such as Inf and NaN inputs, has extensive formatting control for the output, and offers the option of SI prefixes instead of engineering notation.
