Frequently Asked Questions
What is the structure of IEEE-754 single precision?
1 Sign bit, 8 Exponent bits (with +127 bias), and 23 Fraction (Mantissa) bits, totaling 32 bits (4 bytes).
Can this represent special values like Infinity and NaN?
Yes! Typing "NaN" or large overflow values displays their standard IEEE-754 bit patterns.
