Uniform vectors
Uniform vectors are vectors whose elements are of the same numeric type.
The are defined by SRFI-4.
However, the type names (such as <s8vector>
) are a Kawa extension.
The type of uniform vectors where each element can contain
a signed 8-bit integer. Represented using an array of <byte> .
|
The type of uniform vectors where each element can contain
an unsigned 8-bit integer. Represented using an array of <byte> ,
but each element is treated as if unsigned.
|
The type of uniform vectors where each element can contain
a signed 16-bit integer. Represented using an array of <short> .
|
The type of uniform vectors where each element can contain
an unsigned 16-bit integer. Represented using an array of <short> ,
but each element is treated as if unsigned.
|
The type of uniform vectors where each element can contain
a signed 32-bit integer. Represented using an array of <int> .
|
The type of uniform vectors where each element can contain
an unsigned 32-bit integer. Represented using an array of <int> ,
but each element is treated as if unsigned.
|
The type of uniform vectors where each element can contain
a signed 64-bit integer. Represented using an array of <long> .
|
The type of uniform vectors where each element can contain
an unsigned 64-bit integer. Represented using an array of <long> ,
but each element is treated as if unsigned.
|
The type of uniform vectors where each element can contain
a 32-bit floating-point real. Represented using an array of <float> .
|
The type of uniform vectors where each element can contain
a 64-bit floating-point real. Represented using an array of <double> .
