Show the binary representation of floating-point numbers in IEEE 754 single and double precision.
IEEE 754 is the standard for floating-point arithmetic used by virtually all modern CPUs. A float has 1 sign bit, 8 exponent bits, and 23 mantissa bits (32-bit). A double has 1 sign bit, 11 exponent bits, and 52 mantissa bits (64-bit). This tool shows the exact binary layout.
