object CommonBits

Determines the maximum number of common most-significant bits in the mantissa of one or numbers. Can be used to compute the double-precision number which is represented by the common bits. If there are no common bits, the number computed is 0.0.

  16. def numCommonMostSigMantissaBits(num1: Long, num2: Long): Int

    This computes the number of common most-significant bits in the mantissas of two double-precision numbers.

    This computes the number of common most-significant bits in the mantissas of two double-precision numbers. It does not count the hidden bit, which is always 1. It does not determine whether the numbers have the same exponent - if they do not, the value computed by this function is meaningless.

    num1

    the first number

    num2

    the second number return the number of common most-significant mantissa bits

  17. def signExpBits(num: Long): Long

    Computes the bit pattern for the sign and exponent of a double-precision number.

    Computes the bit pattern for the sign and exponent of a double-precision number.

    num

    return the bit pattern for the sign and exponent
