 #### Added
 - Add `YYJSON_WRITE_FP_TO_FLOAT` flag to write real numbers using single-precison.
 - Add `YYJSON_WRITE_FP_TO_FIXED(prec)` flag to write real numbers using fix-point notation.
-- Add `set_fp_to_fixed(val)` and `set_fp_to_prec(val, prec)` functions to control the output format of a specific number.
-- Add `set_str_noesc(val)` function to skip escaping for a specific string during writing.
+- Add `set_fp_to_float()` and `set_fp_to_fixed()` functions to control the output format of a specific number.
+- Add `set_str_noesc()` function to skip escaping for a specific string during writing.
