Bit32 Library

Bit Divide:

<int> bit.bdiv(<uint> dividend, <uint> divisor)
  • Divides dividend by divisor, remainder is not returned.

Bit Add:

<int> bit.badd(<uint> a, <uint> b)
  • Adds a with b, allows overflows.

Bit Subtract:

<int> bit.bsub(<uint> a, <uint> b)
  • Subtracts a with b, allows overflows.

Bit Multiply:

<int> bit.bmul(<uint> a, <uint> b)
  • Multiplies a using b, allows overflows.

Bit And:

<int> bit.band(<uint> x, <uint> disp)
  • Returns the bitwise and of its operands.

Bit Or:

<int> bit.bor(<uint> x, <uint> disp)
  • Returns the bitwise or of its operands.

Bit Xor:

<int> bit.bxor(<uint> x, <uint> disp)
  • Returns the bitwise exclusive or of its operands.

Bit Not:

<int> bit.bnot(<uint> x)
  • Returns the bitwise negation of x.

To Hex:

<string> bit.tohex(<uint> val)
  • Returns val to a hex string.

To Bit:

<int> bit.tobit(<uint> val)
  • Returns val into proper form for bitwise operations.

Left Shift:

<int> bit.lshift(<uint> x, <uint> disp)
  • Returns the number x shifted disp bits to the left.

Right Shift:

<int> bit.rshift(<uint> x, <uint> disp)
  • Returns the number x shifted disp bits to the left.

Arithmetic Shift:

<int> bit.arshift(<int> x, <int> disp)

  • Returns the number x shifted disp bits to the right. The number disp may be any representable integer. Negative displacements shift to the left.

    • This shift operation is what is called an arithmetic shift. Vacant bits on the left are filled with copies of the higher bit of x; vacant bits on the right are filled with zeros. In particular, displacements with absolute values higher than 31 result in zero or 0xFFFFFFFF (all original bits are shifted out).
