fixedSIntBigUnsignedShiftRight
fixedSIntBigUnsignedShiftRight(
value,count,bitWidth):bigint
Defined in: packages/math-numbers/src/fixed-int-big/fixed-sint-big-unsigned-shift-right.ts:20
Logical right shift of a bitWidth-bit two’s-complement integer: zeros fill
from the left, so -1n at 8 bits shifted by one is 127n, not -1n.
This is the one right shift that needs bitWidth. “Fill with zeros from the
left” presupposes a leftmost bit, and a bigint has none — a negative one
behaves as an infinite run of sign bits. The width is what makes the top bit
exist, so the value is read as a pattern, shifted, and read back.
Parameters
Section titled “Parameters”bigint
The value to shift.
number
Bit positions to shift by; non-negative.
bitWidth
Section titled “bitWidth”number
Width of the integer, in bits.
Returns
Section titled “Returns”bigint
Throws
Section titled “Throws”When count is negative or not a safe integer, or
bitWidth is not a non-negative safe integer.
