Formula

Formula is one of the form types in the CubeDrive. CubeDrive allows the user to define the formula in the field. It is a concise way of expressing information symbolically. The flexible of formulas has many effects on data collection:

• It can improve the efficiency to fill the form, automatically calculate the data, and display the content based on some logic.
• Reduce error in the calculate process.

Setup formula

When creating a new form, you can drag the Formula field type from the field list and drop to the form design center panel. You also need set the formula property on the right panel.

To setup a formula, you need enter the format with "=" start in the formula text field. The related information will be popuped when you type the data.

Examples

• =${'Number'}*${'Number2'}*1.13
• =SUM(${'Number'},${'Number2'})
• =PRODUCT(${'Number'},${'Currency'})
• =INT(YEARFRAC(${'birthdate'},TODAY()))
• =IF(${'Number'}>12, "Teenager", "Kid")

Functions

Here lists the supported formulas at this moment.

• + - * /
  Syntax: =(${'Number'}+${'Number2'})*1.1
  User + - * / to process the basic math calculation.
• ABS
  Syntax: =ABS(${'Number'})
  Returns the absolute value of the given number.
• AVERAGE
  Syntax: =AVERAGE(${'Number'},${'Number2'}, ...)

  Syntax: =CONCATENATE(${'text1'},${'text2'}, ...)
  Combines several text strings into one string.
• DEGREES
  Syntax: =DEGREES(${'Number'})
  This function converts radians into degrees.
• EXP
  Syntax: =EXP(${'Number'})
  Returns a Double specifying e (the base of natural logarithms) raised to a power.
• IF
  Syntax: =IF(${'Number'}>12, "Teenager", "Kid")
  Returns one value if a condition evaluates to TRUE and another value if it evaluates to FALSE. .
• INT

• PRODUCT
  Syntax: =PRODUCT(${'Number'},${'Number2'}, ...)
  Returns the multiple of corresponding array numbers
• RADIANS
  Syntax: =RADIANS(${'angle'})
  Converts degrees to radians.
• RAND
  Syntax: =RAND()
  Returns a random number between 0 and 1.
• SQRT
