Section: Type Conversion Functions
y = uint64(x)
where x is an n-dimensional numerical array. Conversion
follows the general C rules (e.g., if x is outside the normal
range for an unsigned 64-bit integer of [0,2^64-1], the least
significant 64 bits of x are used after conversion to an integer).
Note that both NaN and Inf both map to 0.
uint64.
--> uint64(200) ans = 200 --> quit
In the next example, an integer outside the range of the type is passed in. The result is the 64 least significant bits of the argument.
--> uint64(40e9) ans = 40000000000 --> quit
In the next example, a negative integer is passed in. The result is the 64 least significant bits of the argument, \emph{after} taking the 2's complement.
--> uint64(-100) ans = 18446744073709551516 --> quit
In the next example, a positive double precision argument is passed in. The result is the unsigned integer that is closest to the argument.
--> uint64(pi) ans = 3 --> quit
In the next example, a complex argument is passed in. The result is the unsigned integer that is closest to the real part of the argument.
--> uint64(5+2*i) ans = 5 --> quit
In the next example, a string argument is passed in. The string argument is converted into an integer array corresponding to the ASCII values of each character.
--> uint64('helo')
ans =
104 101 108 111

quit
In the last example, a cell-array is passed in. For cell-arrays and structure arrays, the result is an error.
--> uint64({4})
Error: Cannot convert cell-arrays to any other type.
