Question

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.

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

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