I created a form for me to do pressure conversions. For example, Atmosphere to psi, inches Hg to inches water, etc....... I am using a NumericUpDown box for the user to input the numeric value to be converted. I noticed when using a larger number such as 2300 to convert psi to bar, for example, it would change the number I entered (2300) in the NumericUpDown box to 100.00. This happens when I use a number larger than 100 in any of the conversions I try. It seems as though the largest number I can put in the NumericUpDown is 100. How can I make it to where I can input any number no matter how large? Thanks!!
