Set a single bit-field in a 64-bit packed value

Set a single bit-field in a 64-bit packed value

Usage

ffi_set_bits64(packed_value, new_value, bit_offset, bit_width)

Arguments

packed_value

Packed value (as double for 64-bit range)

new_value

New value for the bit-field

bit_offset

Bit offset from LSB (0-based)

bit_width

Number of bits in the field

Value

Modified packed value as double

Examples

packed <- ffi_pack_bits64(c(1L, 5L, 12L), c(1L, 3L, 4L))
new_packed <- ffi_set_bits64(packed, 7L, 1L, 3L) # Set mode to 7
ffi_extract_bits64(new_packed, 1L, 3L) # 7
#> [1] 7
