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?
As per the float and real (Transact-SQL) float is an approximate data type. But also in the same article it is being mentioned that float has precision of 15 digits.
I have a binary file that I read byte by byte. I come acros开发者_JAVA百科s a section that is 8 bytes long, holding a double precision float (little endian). I can\'t figure out how to read this in a
Currently I have some code in PARI/GP which implements computing values of a sequence based on a recurrence. All the numbers in this sequence are between 0 and 1 and high precision is important (at le
I have a working Matlab C code (mex files) which currently uses double precision. Thus I replaced double *datOut = mxGetPr(mxOut) by float *datOut = (float*)mxGetData(mxOut);,
I have medium size C99 program which uses long double type (80bit) for floating-point computation. I want to improve precision with new GCC 4.6 extension __float128. As I get, it is a software-emulate
I have an issue, heh. I\'m doing some calcs with bitcoins in PHP. When I call to the API, I get back JSON with bitcoin values. They are strings with a precision of 1millionth of a decimal.
I was wondering whether, under specific conditions, it is possible to remove floating point errors without resorting to arbitrary-precision datatypes.
Is there a Java library anywhere that can perform computations on IEEE 754 half-precision numbers or convert them to and from double-precision?
Can someone give me an example of a floating point number (double precision), that needs more than 16 significant decimal digits to represent it?
