Controlling iostream display behaviour.

[oRion]

I am trying to control how the scientific notation in VC++ display when I call it. It seems that iostream have a default behaviour how it should look like. I can't seems to be able to control it. For example, the scientific notation of the exponent have to be 3 digits long. There could only be 1.23E+003, where I wanted it to display 12.3E+002 , I can't seems to do that. Is there a library available that allows this to be implemented easily, or I have to write my own stream?I hope that is a easy way to do it. Any suggest from anyone? Just Danny

Have you tried using the iostream format flags? Don't remember excatly but you could use the flags to format the output. Eg. cout<May the Source be with you Sonork ID 100.9997 sijinjoseph

Thanks for the reply. I can set it using setprecision() and setw(), but I can't change it's behaviour. I mean I like my scientific notation to have 2 digits before the decimal points not the default( ie. 1.23E+010) , I was hoping to get 12.34E+009 . Hope u can understand what I mean.I am converting a code from FORTRAN which allows this to happen. X|

Do you have to use cout?? You could do what you want with printf() May the Source be with you Sonork ID 100.9997 sijinjoseph
