This looks silly....but can't figure out. I need to get a float type value from a string value.

Why is the float value rounding up. For example

when i give 123456.488 it results in 123456.484
when i give 988800.45 it results in 988800.44

String sFloatSales = "123456.488";
float fFloatSales1 = Float.parseFloat(sFloatSales);
float fFloatSales2 = Float.valueOf(sFloatSales).floatValue();

Please reply.

Float values only have 6 or 7 digits of accuracy anyway, so the differences you see there aren't significant. If they are significant to you then you should be using double instead of float.
 
I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link: http://aspose.com
