WebbSimilarly, there are gaps between any two single-precision numbers. If x has type single, eps(x) returns the distance between x and the next larger single-precision number. For example, x = single(5); eps(x) returns ans = 4.7684e-07 Note that this result is larger than eps(5). Because there are fewer single-precision numbers than double-precision WebbYou can convert other numeric data, characters or strings, and logical data to double precision using the MATLAB function, double. This example converts a signed integer to double-precision floating point: y = int64 (-589324077574); % Create a 64-bit integer x = double (y) % Convert to double x = -5.8932e+11. chrono cross tower of geddon https://daisyscentscandles.com
