INTSM – Integer number bit shift and mask

Block SymbolLicensing group: STANDARD

Function Description
The INTSM block performs bit shift of input value i by shift bits right (if shift is positive) or left (if shift is negative). Free space resulting from shifting is filled with zeros.

Output value n is calculated as bitwise AND of shifted input i and bit mask mask.

Typical application of this block is extraction of one or more adjacent bits from a given position in integer register which was read from some external system.

Input

i	Integer value to shift and mask $↓$ -9.22337E+18 $↑$ 9.22337E+18	Large (I64)

Parameters

shift	Bit shift (negative=left, positive=right) $↓$ -63 $↑$ 63	Long (I32)
mask	Bit mask (applied after bit shift) $↓$ 0 $↑$ 4294970000 $⊙$ 4294967295	Large (I64)
vtype	Output numeric type $⊙$ 4	Long (I32)
	–- ... 2 .... Byte (U8) 3 .... Short (I16) 4 .... Long (I32) 5 .... Word (U16) 6 .... DWord (U32) –- ... –- ... –- ... 10 ... Large (I64)

Output

n	Resulting integer value	Large (I64)
