Convert Amiga integers into raw values
Convert 8, 16, or 32-bit signed or unsigned integer values into raw data, conform Amiga specifications.
amigaIntToRaw(x, bits = 8, signed = F)
x |
A vector of class |
bits |
Number of bits that represents the integer value. Should be 8 or a positive multitude of 8. |
signed |
A |
The Commodore Amiga has specified the following data formats to represent integer data: BYTE (signed 8-bit integer), UBYTE (unsigned 8-bit integer), WORD (signed 16-bit integer), UWORD (unsigned 16-bit integer), LONG (signed 32-bit integer), ULONG, (unsigned 32-bit integer). This function converts such integers into raw data.
Returns (a vector of) raw data, representing
the integer value(s) conform Amiga specifications.

## some unsigned 8-bit integers: ubyte <- sample.int(255, 100, TRUE) ## The same values as raw data: amigaIntToRaw(ubyte) ## some signed 8-bit integers: byte <- sample.int(255, 100, TRUE) - 128 ## The same values as raw data: amigaIntToRaw(byte, signed = TRUE) ## some signed 16-bit integers: word <- sample.int(2^16, 100, TRUE) - 2^15 ## The same values as raw data: amigaIntToRaw(word, 16, TRUE) ## note that 16-bit integers require ## twice as many raw values: length(amigaIntToRaw(word, 16, TRUE)) length(amigaIntToRaw(byte, 8, TRUE))
