Say I have some vertice values which I am reading into my app as a NSString :

-7501.6 -6198.2 834.939 -5547.66 -6348.32 2122.65

The values in the source are always 6 figures in length.

I need to pass these exact values to OpenGL. If I try to cast as a float (using NSString floatValue) then, as expected, I get an approximate value for each float due to the inexact nature of a float :

-7501.600098, -6198.200195, 834.939026 -5547.660156, -6348.319824, 2122.649902

Can anyone suggest a way that I can get these values into OpenGL and retain their exact initial integrity ?

Thank you.

    maybe this: NSString to NSNumber could help.
