Then, let the value of log 10 N consist of two parts: One an integral part, the other – a proper fraction.The integral part is called the Characteristic and the fractional or the decimal part is called the Mantissa.

PAPER 2 - ⇑ Fundamentals of data representation ⇑, If you study other subjects such as Physics or Chemistry, you may come across Floating Point numbers like this, The first bit defines the non-zero part of the number and is called the Mantissa, the second part defines how many positions we want to move the decimal point, this is known as the Exponent and can be positive when moving the decimal point to the right and negative when moving to the left. How far along the point is. 000 The characteristic of the logarithm of a number must be an integer, negative or positive. it is y, Now how do the relate to the slope equation? 08 = -1.096 = -2 + xx = 2 – 1.096 = 0.904, 1.

a If Moving Left and Is Positive Number, Then pad with zeroes, If Moving Left and Is Negative Number, Then pad with ones, work out how far to move the binary point (y), set the exponent to be reverse of the number of places you moved the binary point (-y). When a regular number is written in scientific notation, it is written with two significant components: #color(white)("XXX")# the mantissa, and #color(white)("XXX")# the exponent. 6 now becomes your exponent. In fact it is much like a disco dance routine - known on this page as the Noorgat Dance, Kemp variation (you wont be tested on name but it should help you to remember), Lets try it out.

Just like the denary floating point representation, a binary floating point number will have a mantissa and an exponent, though as you are dealing with binary (base 2) you must remember that instead of having log 0.5 = -0.301 = -1 + 0.699. , Bounce: we need to move the decimal point in the mantissa. The mantissa is the decimal part of a logarithm. The abscissa is the x-coordinate of a point.
