IEEE 754 Gleitkommazahl-Konverter

IEEE 754 Gleitkommazahl-Konverter

Explore how computers represent decimal numbers in binary with this interactive IEEE 754 converter. Enter any decimal number and instantly see its binary representation broken down into sign, exponent, and mantissa components.

Anwendung

1. Enter a decimal number in the input field (e.g., 3.14, -0.1, 255).

2. Select the precision: Half (16-bit), Single (32-bit), or Double (64-bit).

3. View the complete bit breakdown showing sign bit, exponent, and mantissa.

4. See the hex representation, biased/unbiased exponent, and reconstruction formula.

5. You can also input binary or hex values to convert back to decimal.
