In all number bases, the radix simply represents the point that separates the integer component from the fractional component in a real number. In decimal notation, the radix is more commonly called a decimal point.

How do you represent floating point number in microprocessor?
It is somewhat complicated (search for the IEEE floating-point representation for more details), but the basic idea is that you have a few bits for the base, and a few bits for the exponent. The numbers are stored in binary, not in decimal, so the base and the exponent are the numbers "a" and "b" in a x 2b.
What are the four essential elements of a number in floating-point notation?
Anumberexpressed as a mantissa value qualified by an exponent value, e.g. (0.123 456,-4) to mean 0.123 456 × 10-4else 0.123 456 × 16-4, etc., depending on the implied radix, i.e. numbers in which the true value is obtained by floating the decimal (or equivalent) point the indicated number of places, four to the left in the above example, producing 0.000 0123 456 if with a decimal radix. Withnormalizationof the mantissas to an appropriate set range (typically to the highestarithmeticvalue less than 1, as illustrated here), this notation allows retention, within a fixed amount of space, of comparable numeric significance over a wide range of numeric size. In external display, it is usual to adopt decimal radix and the convention of using E preceding the exponent, e.g. 0.987 6 E + 12 to mean 0.987 6 × 1012.Read more:floating-point-number-3
When is the modulus of a number equal to its radix?
The radix is a property of a numerical system, not an individual number. It is the number of different digits (or characters) used by the system to represent all numbers. Thus the radix of the binary system is 2: 0 and 1 the radix of the octal system is 8: 0,1,2,3,4,5,6 and 7 the radix of the decimal system is 10: 0,1,2,3,4,5,6,7,8 and 9 and so on. Since a number cannot have a radix, the question does not make sense.
What is the smallest 7-digit number?
1.000.000 (a million) is the smallest 7-digit number in radix 10 (decimal number). Here are some result of converted value form other bases : * Radix 2 : 26 = 128 * Radix 8 : 86 = 262.144 * Radix 16 : 166 = 16.777.216
What is the floating-point notation for 25.611?
It is 2.5611*101
What is the utility of floating point representation of numbers?
A floating point number is, in normal mathematical terms, a real number. It's of the form: 1.0, 64.369, -55.5555555, and so forth. It basically means that the number can have a number a digits after a decimal point.
What is floating point error?
A method for storing and calculating numbers in which the decimal points do not line up as in fixed point numbers. The significant digits are stored as a unit called the "mantissa," and the location of the radix point (decimal point in base 10) is stored in a separate unit called the "exponent." Floating point methods are used for calculating a large range of numbers quickly. Floating point operations can be implemented in hardware (math coprocessor), or they can be done in software. In large systems, they can also be performed in a separate floating point processor that is connected to the main processor via a channel.

How many bits are used in double precision floating point format number representation?
Depends on the format IEEE double precision floating point is 64 bits. But all sorts of other sizes have been used IBM 7094 double precision floating point was 72 bits CDC 6600 double precision floating point was 120 bits Sperry UNIVAC 1110 double precision floating point was 72 bits the DEC VAX had about half a dozen different floating point formats varying from 32 bits to 128 bits the IBM 1620 had floating point sizes from 4 decimal digits to 102 decimal digits (yes digits not bits).
Floating point representation in binary why is it important to represent and how the decimal is placed in the binary?
It's a tricky area: Decimal numbers can be represented exactly. In contrast, numbers like 1.1 do not have an exact representation in binary floating point. End users typically would not expect 1.1 to display as 1.1000000000000001 as it does with binary floating point. The exactness carries over into arithmetic. In decimal floating point, 0.1 + 0.1 + 0.1 - 0.3 is exactly equal to zero. In binary floating point, the result is 5.5511151231257827e-017. While near to zero, the differences prevent reliable equality testing and differences can accumulate. For this reason, decimal is preferred in accounting applications which have strict equality invariants. So you have to be carefull how you store floating point decimals in binary. It can also be used in a fraction. It must be simplufied then reduced and multiplied.
