Details
The format parameter uses zeros (0), the decimal point, polarity sign, and exponents to define how the input
field is formatted. The format parameter can include the options shown in the following table.
Option Description Examples
E
Include the E to display the value exponentially
0.00000e+0
+
Allows operators to enter positive or negative values; if the
"+" sign is not included, the operator cannot enter a
negative value
+0.00
0
Defines the digit positions for the value; you can use up to
six zeros (0)
+00.0000e+00
.
Include to have a decimal point appear in the value
+0.00
The default parameter is the value shown when the value is first displayed.
The minimum and maximum parameters can be used to limit the values that can be entered. When + is not
selected for format, the minimum limit must be more than or equal to zero (0). When limits are used, you
cannot enter values above or below these limits.
The input value is limited to ±1e37.
Before calling display.inputvalue(), you should send a message prompt to the operator using
display.prompt(). Make sure to position the cursor where the edit field should appear.
After this command is sent, script execution pauses until you enter a value and press the ENTER key.
For positive and negative entry (plus sign (+) used for the value field and/or the exponent field), polarity of a
nonzero value or exponent can be toggled by positioning the cursor on the polarity sign and turning the
navigation wheel . Polarity will also toggle when using the navigation wheel to decrease or increase the
value or exponent past zero. A zero (0) value or exponent (for example, +00) is always positive and cannot be
toggled to negative polarity.
After executing this command and pressing the EXIT (LOCAL) key, the function returns nil.
Example
display.clear()
display.settext("Enter value between$N -0.10 and 2.00: ")
value = display.inputvalue("+0.00", 0.5, -0.1, 2.0)
print("Value entered = ", value)
Displays an editable field (+0.50) for operator input. The valid input range is -0.10 to +2.00, with a default of
0.50.
Output:
Value entered = 1.35000e+00
