printf format %e does not work.

[danielchai]

Hi All,

I have a float number data = 25.99978

and I want to using sprintf to format it to %e.

sprintf(pointer, "%15.8e", data);

but pointer always 2.5e+01.

How should I do so it can format the width to 15 and precision to 8.

Thank you.

I figure it out. The exel format it automatically.
