decimal separator to display the whole value, then the whole value will overrun the fractional
value. For example, if you try to display a value of 112.64 in #.##, you will see 112.
• In Hexa and Binary formats, if you have more # characters than you need to display the value,
then the runtime project will fill in with leading zeroes. If you have less characters than you need,
then the value will simply be truncated.
• In Auto format, the runtime project will ignore the number of # characters and display the entire
numeric or string value. Numeric values will be displayed in decimal format with their complete
whole and fractional values, regardless of the placement of the decimal separator in the ### text.
Given an exceptionally large value or long string, this may disrupt the layout of your screens.

be formatted and displayed on-screen. Available options include Decimal, Hexa (i.e., hexadecimal), Binary

SetDecimalPoints function.
This option does not actually change the specified tag or expression in any way. For example, Tag/Expression
is set to a tag of Integer type, Input Enabled is checked, and Fmt is set to Hexa. You may input a new value in
hexadecimal format, but it is saved in your project database as an integer.
• Input Enabled checkbox: Click (check) this option to allow user input to the specified tag. Disable (uncheck)
this option to only display the output from the specified tag or expression.
• Back to text: Click to go back to the object properties of the underlying Text object.
• Minimum Value field: Enter a minimum value for the tag associated with this Text object. A user will not be
permitted to input a number lower than this value.
• Maximum Value field: Enter a maximum value for the tag associated with this Text object. A user will not be
permitted to input a number greater than this value.
• Password checkbox: Click (check) this option to hide password text entries by replacing the text with
asterisks (*).
• Confirm checkbox: Click (check) this option to require users to confirm any new values set during runtime.
• Auto Size checkbox: Click (check) this option to automatically resize the Text object to fit the output. This
option is not available if Input Enabled is checked (see above).
• E-Sign checkbox: When this option is checked, the user will be prompted to enter the Electronic Signature
before changing the tag value.
