I was looking for a way to co开发者_Go百科nvert IEEE floating point numbers to IBM floating point format for a old system we are using.
Can anyone explain to me in detail how this log2 function works: inline float fast_log2 (float val) { int * constexp_ptr = reinterpret_cast <int *> (&a开发者_JAVA百科mp;val);
Is there any way I can read bytes of a float value in JS? What I need is to write a raw FLOAT or DOUBLE value into some binary format I need to make, so is there any way to get a byte-by-byte IEEE 754
I have a decent underst开发者_运维问答anding of how floating point works, but I want to know how the specific exponent and mantissa sizes were decided upon. Are they optimal in some way? How can optim
Unexpected results in Firebug console. Why in this operation: 1.7E16+2 the last number is 2 and in 1.7E16+3 operation the last n开发者_如何学编程umber is 4 :D This is a JavaScript Bug?
I\'m revisiting a question (How to test if numeric conversion will change value?) that as far as I was concerned was fully solved. The problem was to detect when a particular numeric value would overf
I\'m looking for a C# equivalent to Java\'s Double.longBitsToDouble method. I have a double value stored in a ulong and I want those bits to be converted 开发者_开发知识库to represent a double. Is the
I\'m working on porting the sqrt function (for 64-bit doubles) from fdlibm to a model-checker tool I\'m using at the moment (cbmc).
i want to use the sqrt implementation of fdlibm. This implementation defines (according to the endianess) some macros for accessing the lower/upper 32-bit of a double) in the following way (here: only
For the purposes of this question, I do not have the ability to use printf facilities (I can\'t tell you why, unfortunately, but let\'s just assume for now that I know what I\'m doing).
