MANTISSA
• Usually the first five bits in the floating point representation.
• Controls the accuracy of the number. More bits for the Mantissa
means that the accuracy will increase.

• Usually the last three bits in the floating point representation.
• Controls the range of the number.

OCTAL
• A form of representing numbers using a base 8 system. This allows
8⁸ numbers to be stored in an 8 bit byte.

OVERFLOW
• Occurs when you try and store a number in floating point that is too
large to store in the allocated amount of bits.

UNDERFLOW
• If you try and store a number that may be too small to store in the
allocated bits.
