Mantissa

The section of a Floating Point Binary value that represents the significant digits of the number

Exponent

The section of a Floating Point Binary value that informs how many places to move the decimal point (the number to the power of 2 to raise the mantissa by)

Normalisation

Maximising the range and precision of floating point binary values. Positive mantissas should start 01, negative mantissas should begin 10

Underflow

When the value is too small to be represented by the number of bits reserved for the data

Overflow

When the value is too large to be represented by the number of bits reserved for the data

Mantissa

The section of a Floating Point Binary value that represents the significant digits of the number

Exponent
