Bit shifting multiplication
Webor by testing the sign bit: uint16 a = original; bool negative = a & 0x8000; Testing the sign bit can also be done on some platforms with a left-shift operation, if the operation produces a carry. uint16 a = original; a = a << 1; // Binary left-shift by 1 bool carry = /* save carry from this calculation*/; bool negative = carry; WebSuppose we have a byte a = 0b11001010. We can shift all of the bits to the left by 4 bits: byte a = (byte) 0b11001010; a = (byte) (a << 4); a == (byte) 0b10100000; // evaluates to …

WebArithmetic shifts can be useful as efficient ways to perform multiplication or division of signed integers by powers of two. Shifting left by n bits on a signed or unsigned binary number has the effect of multiplying it by 2 n. WebSep 19, 2024 · Bitwise operators See also Short description Describes the operators that perform arithmetic in PowerShell. Long description Arithmetic operators calculate numeric values. You can use one or more arithmetic operators to add, subtract, multiply, and divide values, and to calculate the remainder (modulus) of a division operation.
