How To Round A Probability Using Floor

When rounding numbers you must first understand the term rounding digit when working with whole numbers and rounding to the closest 10 the rounding digit is the second number from the right or the 10 s place when rounding to the nearest hundred the third place from the right is the rounding digit or the 100 s place.

How to round a probability using floor.

Page 556 the rounding rule for the intercept and slope round the values of a and b to three decimal places. This kind of rounding is sometimes called rounding toward negative infinity. The following example illustrates the math floor double method and contrasts it with the ceiling double method. Rules for rounding whole numbers.

Double values 7 03 7 64 0 12 0 12. The probability for beeing rounded to 7 is 0 1 and the probability to be rounded to 6 is 1 0 1. So if i run this rounding experiment infinite times the average of all integer results should be 6 1 again. It is the most common rounding mode of dsp processors because it requires no hardware to implement.

Very similar to round x 0 1. For example say you started with 0 and added 0 3 to that one hundred times while rounding the running total between every addition. Round towards minus infinity. By using the floor function it will only be rounded up if the random number between 0 and 1 is enough to bring it up to the next highest.

Floor rounding is often called truncation when used with integers and fixed point numbers that are represented in two s complement. For example 1 6 would be rounded to 1 with probability 0 4 and to 2 with probability 0 6. Floor returns the integer value less than or equal to the value passed in. The behavior of this method follows ieee standard 754 section 4.

Not in book the rounding rule for the correlation coefficient round the value of r to three decimal places. Oddly round x 0 1 returns almost the same value as floor.
