What are the three parts of a floating-point number?
Assuming you're asking about IEEE-754 floating-point numbers, then the three parts are base, digits, and exponent.
In a floating point number representation the number with excess 64 code and base as 16 the number 16e-65 is represented as?
"In a floating point number representation, the number with excess 64 code and base as 16, the number 16e-65 is represented as: " This the minimum re-presentable positive number.
What is a floating number?
A floating point number is one that contains an integer as well as a fractional part, for example 101.3625. These are often represented by their scientific notations as well, such as 1.013625E2
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 data type is weight?
Weight is typically represented by a floating point type (a real number). However, depending on the precision required by the programmer, a weight can also be represented as an unsigned integral (a positive whole number). Note that floating point types are always signed.
How are floating point numbers handled as binary numbers?
Floating point numbers are typically stored as numbers in scientific notation, but in base 2. A certain number of bits represent the mantissa, other bits represent the exponent. - This is a highly simplified explanation; there are several complications in the IEEE floating point format (or other similar formats).Floating point numbers are typically stored as numbers in scientific notation, but in base 2.

How does a computer represent floating point numbers?
In Computing, Floating Point refers to a method of representing an estimate of a real number in a way which has the ability to support a large range of values.
What does the acronym FPU represent?
Floating Point Unit
Does the length of a vector arrow represent its magnitude and the point its direction?
True
Why is the size of a decimal number not necessarily determined by the number of decimal places notated?
Digits after (to the right of) the decimal point contribute to the accuracy of the number, not its magnitude (or size). So only the digits to the left of the decimal point contribute to the magnitude. Digits after (to the right of) the decimal point contribute to the accuracy of the number, not its magnitude (or size). So only the digits to the left of the decimal point contribute to the magnitude.

What are the 3 parts of a floating part number?
If you mean floating point number, they are significand, base and exponent.
In your C plus plus program when you enter a decimal for the wholesale price 7.99 for example your program just keeps repeating the next cout line indefinately how do you make it stop?
If your program is looping based on a floating point value, you need to consider that floating point values do not exactly represent the intended decimal value. Any program that makes decisions based on the value of a floating point number must consider truncation error.For instance, 0.110 is 0.00011001100110011...2. Since a floating point register cannot represent an infinite number of bits, this might actually be something else, such as 0.09999999999710, depending on your particular resolution.
What of a real number is the point on a number line that corresponds to a real number?
magnitude
Represent (178.1875)10 in single and double precision floating point format?
balls
Is floating point is exponentional number?
Yes.Yes.Yes.Yes.
What is the floating point unit used for on the processor system?
"Floating Point" refers to the decimal point. Since there can be any number of digits before and after the decimal, the point "floats". The floating point unit performs arithmetic operations on decimal numbers.
If you are given the magnitude of a vector but no directionhow can you represent this vector graphically?
You cannot, unless it is a null vector. As a point.
