About IEEE 754 Floating Point
IEEE 754 is the standard for floating-point arithmetic. It represents real numbers using a sign bit, exponent, and mantissa (significand). This calculator supports 32-bit single precision format.
Floating Point Tips
- Sign Bit: 0 = positive, 1 = negative
- Exponent: Biased by 127 (32-bit) or 1023 (64-bit)
- Mantissa: Normalized binary fraction (1.xxx)
- Special Values: ±0, ±∞, NaN
- Precision: 32-bit: ~7 digits, 64-bit: ~15 digits
- Range: ±3.4×10³⁸ (32-bit), ±1.8×10³⁰⁸ (64-bit)
