          CPU_CHAR  *Str_FmtNbr_32 (CPU_FP32      nbr,
                                    CPU_INT08U    nbr_dig,
                                    CPU_INT08U    nbr_dp,

                                    CPU_CHAR     *pstr);

Arguments

nbr

Number to format into a string.

...

Available only if LIB_STR_CFG_FP_EN is DEF_ENABLED in lib_cfg.h (see section 5-1).

Notes / Warnings

For any unsuccessful string format or errors, an invalid string of question marks ('?') will be formatted, where the number of question marks is determined by the number of digits (nbr_dig) and number of decimal point digits (nbr_dp) to format. Also, whenever an invalid string is formatted for any reason, a NULL pointer is returned.

...

Character array size must be >= (nbr_dig +
nbr_dp +
1 negative sign +
1 decimal point +
1 NUL terminator) characters

Example Usage

          CPU_CHAR   AppBuf[20];
          CPU_CHAR  *pstr;
         


          pstr = Str_FmtNbr_32((CPU_FP32   )-1234.5678,
                               (CPU_INT08U ) 5,
                               (CPU_INT08U ) 2,
                               (CPU_CHAR   ) ' ',
                               (CPU_BOOLEAN) DEF_NO,
                               (CPU_BOOLEAN) DEF_YES,
                               (CPU_CHAR  *)&AppBuf[0]);
