Function bits_set

test/hex_float_test.cpp:689–696

Sets the bits from MSB to LSB of the significand part of a float. For example 0 would set the bit 23 (counting from LSB to MSB), and 1 would set the 22nd bit.

// For example 0 would set the bit 23 (counting from LSB to MSB),
// and 1 would set the 22nd bit.
uint32_t bits_set(const std::vector<uint32_t>& bits) {
  const uint32_t top_bit = 1u << 22u;
  uint32_t val = 0;
  for (uint32_t i : bits) {
    val |= top_bit >> i;
  }
  return val;
}

// The same as bits_set but for a Float16 value instead of 32-bit floating
// point.
