machine epsilon造句

例句與造句

  1. Numerical analysis uses machine epsilon to study the effects of rounding error.
  2. Computing machine epsilon is often given as a textbook exercise.
  3. Since machine epsilon is a bound for relative error, it suffices to consider numbers with exponent e = 0.
  4. For a number system and a rounding procedure, machine epsilon is the maximum relative error of the chosen rounding procedure.
  5. Using this calculated step size with an error tolerance of less than half of the machine epsilon yields a symplectic integration.
  6. It's difficult to find machine epsilon in a sentence. 用machine epsilon造句挺難的
  7. Most numerical analysts use the words " machine epsilon " and " unit roundoff " interchangeably with this meaning.
  8. In languages that allow type punning and always use IEEE 754-1985, we can exploit this to compute a machine epsilon in constant time.
  9. The following examples compute machine epsilon in the sense of the spacing of the floating point numbers at 1 rather than in the sense of the unit roundoff.
  10. For example, the comparisons for the medcouple kernel function should be done within machine epsilon, as well as the order comparisons in the greater _ h and less _ h functions.
  11. The following different definition is much more widespread outside academia : " Machine epsilon is defined as the smallest number that, when added to one, yields a result different from one ."
  12. In step " n " of the Euler method, the rounding error is roughly of the magnitude ? " y " " n " where ? is the machine epsilon.
  13. The 1 + a in the denominator is negligible compared to the numerator, so it is left off for expediency, and just b ^ {-( p-1 ) } / 2 is taken as machine epsilon.
  14. The definition given here for " machine epsilon " is the one used by Prof . James Demmel in lecture scripts and his " LAPACK " linear algebra package, and by numerics research papers and some scientific computing software.
  15. As has been shown here, the relative error is worst for numbers that round to 1, so machine epsilon also is called " unit roundoff " meaning roughly " the maximum error that can occur when rounding to the unit value ".
  16. In a strict sense the term " machine epsilon " means the "'1 + eps "'accuracy directly supported by the processor ( or coprocessor ), not some "'1 + eps "'accuracy supported by a specific compiler for a specific operating system, unless it's known to use the best format.
