What is the way to round off a variable and store it rounded off so that if it goes to DB, it goes off exactly as it was being displayed.
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:
