Question

IEEE 754 single precision uses:

• A. 16 bits
• B. 32 bits
• C. 64 bits
• D. 128 bits

Hint:

Remember these IEEE 754 standards: Single Precision = 32 bits Double Precision = 64 bits

Answer 1

The Correct Option is B

Concept: IEEE 754 is the internationally accepted standard for floating-point representation in computers. It specifies how real numbers are stored and manipulated in hardware and software. The standard defines different precisions such as: Single Precision and Double Precision with fixed bit allocations.

Step 1: Recall IEEE 754 single precision format.
Single precision uses: \[ 32 \text{ bits} \] These bits are divided as: \[ 1 \text{ sign bit} \] \[ 8 \text{ exponent bits} \] \[ 23 \text{ mantissa bits} \]

Step 2: Calculate total bits.
\[ 1+8+23=32 \]

Step 3: Compare with given options.
The correct choice is: \[ 32 \text{ bits} \] \[ \boxed{32 \text{ bits}} \]
