Hi, I am try to write a formated number into a file. For example, Writing 6.661999999999944*10^-6 as 6.66200E-06 . If I use ScientificForm and can see the format 6.66200E-06 in mathematica, however when i am trying to write it into a file like the what i see in mathematica, the I see ScientificForm instead of the result i desired. How to tackle this problem?
