Kenneth created a system that stores numbers using floating‑point representation, it has eight bits for the mantissa and four bits for the exponent.Kenneth decided to increase the number of bits used to 16, this means that:

• Precision of numbers represented will increase, range of numbers represented will decrease

• Range of numbers represented will decrease, precision of numbers represented will decrease

• Precision of numbers represented will decrease, range of numbers represented will increase

• Precision of numbers represented will increase, range of numbers represented will increase
