Floats and scientific notation

I am creating 1D and 2D array from a file that contains lines that look like this:

42857000 -923070 0 0 -7887 428570 -546190 -4285700 546190 0 -6.5 -0.15384 6.5 0.15384 0.007 0 0 42857000 360570 0

When I populate the arrays from the file, they get converted to scientific notation:

42857000 >>>>> 4.2857000e+007 etc!!!

Is there anyway to stop this?

My arrays are defined as follows:

float aMatrix[DEFROWS][DEFCOLS] = {0.0};
float bMatrix[DEFCOLS] = {0.0};

This issue is causing my app to crash.

Thanks.

Is it crashing on reading it in or sending it out? Are you using cout or printf? One extremely common way to crash it to use printf with a %d and send it a floating point value.

I assume this is just from printing with cout. If that's the case, use std::fixed:

std::cout << std::fixed << whateverNumberCurrentlyInScientific;
