What is a fractional value?
A fraction is a numerical number that is a portion of a whole. It is calculated by dividing a total into the number of pieces. 12 symbolizes half of a complete number or an item, for example.
Fractional values can be stored in floating-point variables, which store integers in a binary form of scientific notation.
Any number may be represented by a decimal fraction, the mantissa, m, multiplied by 10 raised to a power, the exponent, e, in scientific notation. [10.13]
