I have created many apps, many have logic built in to input and/or auto calculate fields like temperature delta T's, ect. When first using the number field type it defaults to integer only. To allow decimal input style I have to select the currency option, then go back to the number style. That is an easy workaround, just be ideal if there was an decimal style option off the get go. Would also be nice if there was an option for a post text for example adding Lbs, or PSI to the end of the input automatically.
Default Integer Number Style Below, notice the circled area.
Below, notice how number style now shows after first selecting currency style, then back to the number style. Notice the decimal that is now in the field circled. It now has a decimal in it. Same style, but this way allows decimal input for temperatures, voltages, pressures, ect. without the currency format.
