Hi, I haven't find easily way to do following: ->> num: 0.00181716 == 1.81716E-3 ->> num == 1.81716E-3 ->> ble: form num == "1.81716E-3" ->> print ble 1.81716E-3 ->> ble: to-string num == "1.81716E-3" ->> print ble 1.81716E-3 ->> I hope I don't need to create some special formatter function, or? ;-) At-least - why conversion functions are not preserving the same value I assigned to num? Thanks, -pekr-
