Problem: the bitwise integer to fixed-point functions (in 7.18a.6.6) do not use the int_fx_t and uint_fx_t integer types; the text in 4.1.7.5 is already correct.

Solution:

• change the Synopsis section of 7.18a.6.6 to read:

  #include <stdfix.h>
  short fract hrbits(int_hr_t n);
  fract rbits(int_r_t n);
  long fract lrbits(int_lr_t n);
  short accum hkbits(int_hk_t n);
  accum kbits(int_k_t n);
  long accum lkbits(int_lk_t n);
  unsigned short fract uhrbits(uint_uhr_t n);
  unsigned fract urbits(uint_ur_t n);
  unsigned long fract ulrbits(uint_ulr_t n);
  unsigned short accum uhkbits(uint_uhk_t n);
  unsigned accum ukbits(uint_uk_t n);
  unsigned long accum ulkbits(uint_ulk_t n);
  

• remove from the of 7.18a.2 the words 'as return types'

• change in 7.18a.2 the first sentence after the list to read:

  The integer types int_fx_t and uint_fx_t are the return types of the corresponding bitsfx functions and are chosen so that the return value can hold all the necessary bits; the fxbits functions use these integer types as types for their parameters.
