Decimal input is first read as a double (about 17 significant digits). Everything is calculated in your browser; nothing you type is uploaded.
Rounding follows IEEE 754: round to nearest, ties to even, including subnormals and overflow to infinity. The exact decimal value is computed with big integers from the stored bits.
0.1 as a single-precision float is 0x3DCCCCCD, whose exact value is 0.100000001490116119384765625.
