WebHow do I convert this 32-bit number to its IEEE single-precision floating-point representation - using what's available in MATLAB? With mentioned value in variable n, I have tried using a combination of nn=dec2hex(n,16) and then hex2num(nn). But it seems that hex2num expects the hexadecimal coding to be double-precision and not single as it … WebMay 27, 2011 · You can cast the value to an integer and back to a double and check the result against the original value: >> x = 1.3; >> x == double (uint64 (x)) ans = 0 >> x = 2; >> x == double (uint64 (x)) ans = 1 Interestingly, R.M.'s approach of using MOD runs faster in a loop and the above casting approach runs faster when vectorized:

WebNov 12, 2013 · Double precision (64-bit) floating point numbers can exactly represent integers up to 2^53 (9,007,199,254,740,992) without losing any accuracy. The maximum array size allowed by MATLAB is far below this number, so there is no risk of indexing errors as a result of floating point precision. Share Improve this answer Follow WebDec 5, 2013 · To convert an array of type “double” to an integer type, you can use a function such as “int64”, which converts the input to a 64-bit integer.
