Is there a way to programmatically retrieve the maximum flo开发者_运维百科at value for php.Akin to FLT_MAX or std::numeric_limits< float >::max() in C / C++?
I am trying to parse a XML File using NSXMLParser, I also have a Container class, in which I have a few instance variables.One of the elements that I am trying to parse in the XML is:
I understand that floating point arithmetic as performed in modern computer systems is not always consistent with real arithmetic.I am trying to contrive a small C# program to demonstrate this. eg:
EDIT: I had made a mistake during the debugging session that lead me to ask this question. The differences I was seeing were in fact in printing a double and in parsing a double (strtod). Stephen\'s a
开发者_C百科In C, what is the difference between these two? float myF = 5.6; printf( \"%i \\n\", (int)myF ); // gives me \"5\"
How can I convert from bytes to float in php? Like in Java int i = (byte3 & 0xff) << 24 | (byte2 & 0xff) &开发者_开发问答lt;< 16 | (byte1 & 0xff) << 8 | byte0 & 0xff;
Say I want a function that takes two floats (x and y), and I want to compare them using not their float representation but rather their bitwise开发者_StackOverflow representation as a 32-bit unsigned
When I read a sheet into a DataTable using the OleDbDataReader, floating point numbers loose their precision.
I am trying to perform broad-phase collision detection with a fixed-grid size approach. Thus, for each entity\'s position: (x,y,z) (each of type float), I need to find which cell does the entity lie i
Is converting Fixed Pt. (fixed n bit for fraction) to IEEE double safe ? ie: does IEEE double format can represent all numbers a fixed point can represent ?
