Have been trying to debug this for hours and no outcome. Please help. Environment: PHP5.3 talking to MSSQL2005/8 with Microsoft MSSQL Driver for PHP
I am writing a program for an embedded hardware that only supports 32-bit single-precision floating-point arithmetic. The algorithm I am implementing, however, requires a 64-bit double-precision addit
I\'m wondering what the best way to fix precision errors is in Java. As you can see in the following example, there are precision errors:
I wrote some parameters (all of type double) to a file for use in performing some complex computations. I write the parameters to the files like so:
No, this is not another \"Why is (1/3.0)*3 != 1\" question. I\'ve been reading about floating-points a lot lately; specifically, how the same calculation might give different results on different arc
This was a question I was asked at my recent interview and I want to know (I don\'t actually remember the theory of the numerical analysis, so please help me :)
I want to write doubles to a file but the string cast reduces the precision. Edit : I don\'t really cast but put the doubles in an ostringstream.
If I do: echo microtime(true); I get the following results: On my local Windows development environment I get a 4 digit precision (1310564569.4162 for example).
I\'ve written a python module for g开发者_如何转开发anglia that is returning response times.The raw times look like this:
this is my first post here and i like to thank all the people that can help me with this simple question: how the casting works in java?
