Tool to convert decimal to ascii.

If you use C, it's as simple as storing the decimal number into a uint8_t and then printing it out as a char.

Some calculators can do it ... there are also websites that will do the same with a quick Google search although I will refrain from recommending any particular one to avoid being flagged as spam.

Here's a code snippet in VHDL, I doubt that it's quite what you are after (it converts binary to ascii) but it gives an idea of the range of valid answers.

Is it the best tool - of course not, but it's good where it's used.

					when PAR_READ =>
						reg_rd <= '1';
						pars_state <= PAR_READ_1; 
					when PAR_READ_1 =>
						if reg_trf_done = '1' then
							v_reg := unsigned(reg_in);						 	 
							if (v_reg(31) = '1') and ((cmnd_char = x"6a") 				-- reg a is 32 bit signed so deal with -ve case 
													or (cmnd_char = x"67") 				-- reg g is interleave accumulator 
													or (cmnd_char = x"71") 				-- reg q is pos_count1 
													or (cmnd_char = x"72") 				-- reg r is pos_count2 
													or (cmnd_char = x"73") 				-- reg s is pos_count3
													) then
								v_reg(31) := '0';
								v_reg(30 downto 0) := ((not v_reg(30 downto 0)) + "0000000000000000000000000000001");  
								isneg <= '1';
								tx_char <= "00101101";			-- negative sign
								tx_wrreq <= '1'; 				-- send it out					
							else
								isneg <= '0';
							end if;								
							reg_val <= v_reg;
							reg_rd <= '0'; 
							ten_pwrs_index <= "1001";		-- points to 1e9	  
							digit <= "0000";  
							nz_sent <= '0';					-- used to prevent leading zeros, set when a character is sent
							pars_state <= PAR_READ_1A; 
						end if;	 
					when PAR_READ_1A =>
						tx_wrreq <= '0';					-- must be cleared after -ve so clear anyway is safe
						pars_state <= PAR_READ_2;
					when PAR_READ_2 => 
						if reg_val >= ten_pwrs(to_integer(ten_pwrs_index)) then
							reg_val <= reg_val - ten_pwrs(to_integer(ten_pwrs_index));
							digit <= digit + 1;
						else
							if (digit > 0) or (nz_sent = '1') or (ten_pwrs_index = 0) then
								tx_char <= std_logic_vector(("0000" & digit) + 48);  
								tx_wrreq <= '1';  
								nz_sent <= '1';
								pars_state <= PAR_READ_3; 
							end if;
							ten_pwrs_index <= ten_pwrs_index - 1;	-- when ls digit will wrap to 15
						end if;
					when PAR_READ_3 =>
						tx_wrreq <= '0';		
						if ten_pwrs_index < 10 then					-- traps the end condition	
							digit <= "0000";
							pars_state <= PAR_READ_2; 
						else
							pars_state <= PAR_SEND_CRLF;	
						end if;	
					when PAR_SEND_CRLF =>
						tx_char <= "00001101";						-- CR
						tx_wrreq <= '1'; 					
						pars_state <= PAR_CRLF_1;
					when PAR_CRLF_1 =>
						tx_char <= "00001010";						-- LF
						tx_wrreq <= '1'; 					
						pars_state <= PAR_CRLF_2;
					when PAR_CRLF_2 =>
						tx_wrreq <= '0'; 
						busy <= '0';
						pars_state <= PAR_IDLE;

So, first of all what do you mean by decimal - this is what I call decimal 4567 - a number represented by tokens for values 0 - 9, but I suspect you mean a numeric value in some code that you want to output as ASCII characters.

If you define the problem better it will be possible to give some answers.

What is your application for the software tool? Embedded in program or stand alone?

float f;

f = 123.45

printf("%f",f);
