Dear All I have a FX2N plc with a 232BD card. I have attached a mutimeter to get values from the same. Now I get "+1.9903E+3" . Please note that the decimal point is floating so I could even get "+123.45E+0". But the total length of the string is always 10. Now I want to convert this string in to either hexadecimal or decimal so that I can compare with the stored data. I tried using HEX and then the BIN command, but it doesnt work for ".". Need help Thanks Vihang P.S: The attachment RS232_Multimeter_Test.zip
