Export assignment imuldw

• imuldw(out: ArrayLike<number>, a: number, b: number): ArrayLike<number>
• imuldw(a: number, b: number): ArrayLike<number>

• Performs multiplication of two signed 32-bit integers and returns an array of two signed 32-bit integers which represents the signed 64-bit integer product.

  Notes

  • When computing the product of 32-bit integer values in double-precision floating-point format (the default JavaScript numeric data type), computing the double word product is necessary in order to avoid exceeding the maximum safe double-precision floating-point integer value.

  Parameters

  • out: ArrayLike<number>

    output array

  • a: number

    integer

  • b: number

    integer

  Returns ArrayLike < number >

  output array

  Example

  var v = imuldw( 0xAAAAAAAA, 0x55555555 );
  // returns [ -477218589, 1908874354 ]
