Description
|
|
|
•
|
The int32(A) functions evaluate each element of A numerically and round the result to the nearest integer value that fits in the specified number of bits.
|
|
•
|
The range of int8 is -2^7 .. 2^7-1 or -128 .. 127
|
|
•
|
The range of int16 is -2^15 .. 2^15-1 or -32768 .. 32767
|
|
•
|
The range of int32 is -2^31 .. 2^31-1 or -2147483648 .. 2147483647
|
|
•
|
The range of int64 is -2^63 .. 2^63-1 or -9223372036854775808 .. 9223372036854775807
|
|
•
|
The range of uint8 is 0 .. 2^8-1 or 0 .. 255
|
|
•
|
The range of uint16 is 0 .. 2^16-1 or 0 .. 65535
|
|
•
|
The range of uint32 is 0 .. 2^32-1 or 0 .. 4294967295
|
|
•
|
The range of uint64 is 0 .. 2^64-1 or 0 .. 18446744073709551615
|
|
•
|
A value under the minimum range is increased to the minimum. A value over the maximum range is reduced to the maximum.
|
|
•
|
If possible, the computation is done using the floating-point hardware of the underlying system using evalhf.
|
|
•
|
Division by zero will be trapped and the maximum integer value for the specified precision is returned instead of raising an error.
