Is it possible to set this, for example to not have 2.4e+002 but 2.4e2? I really have been searching for this hard, and know how to set with precision the number preceding "e" but the exponent just isn't clear as to what I can do with.No where that I have searched, have I found how to specify this expoenent. I would like to use a integer to specify the number of characters to be presented after "e" and somehow to not include "+" when it is positive, but ofcourse "-" to be included when the exponent is negative.
This is what I want the floating value to be represented in accordance to the following examples:
134.5 ...... 1.345e2
-21.5 ...... -2.1e1
-0.005...... 5e-3
By the way, the numbers on the left side of these examples are presented as strings, so I can use that quite easily to bound the number of needed characters left of "e". Could this at all be done using the library functions in C, or should I just right the code myself, which might take some time. Right now, doing printf("%e",fl) will yield too many zeros and un-needed plus sign in the exponent if need be. Anyway to get rid of this in say, less than 20 lines of code using library functions?
