IEEE 754 Floating Point

Inspect how f32 and f64 values are encoded as sign, exponent, and fraction bits.

Controls:

• Click F32 or F64 to switch formats.
• Click any bit to toggle it.
• Use the preset buttons for zero, one, pi, infinity, NaN, and the smallest normal value.
• Keyboard: F toggles format, 3 selects f32, 6 selects f64, arrow keys move the selected bit, and Space or Enter toggles it.
• Shortcuts: S/N toggles sign, Z zero, O/1 one, P pi, I infinity, Q NaN, and M minimum normal.
• Watch the raw exponent, hidden bit, hexadecimal bytes, decimal value, and scientific notation update together.
