How to calculate?
  • Calculation can be made only in item type “Result”
  • Enter the calculation formula using fields values as field_1(Field 1 value), field_2(Field 2 value) … field_n(Field n value)
  • To print the calculation result, use {result} in the field “Result”
    Simple calculation: field_1 + field_2
Which calculation operations are included?
        • / – Simple arithmetic operations
  • Math.abs(x) – Returns the absolute value of x
  • Math.ceil(x) – Returns x, rounded upwards to the nearest integer
  • Math.exp(x) – Returns the value of Ex
  • Math.floor(x) – Returns x, rounded downwards to the nearest integer
  • Math.log(x) – Returns the natural logarithm (base E) of x
  • Math.pow(x, y) – Returns the value of x to the power of y
  • Math.round(x) – Rounds x to the nearest integer
  • Math.sqrt(x) – Returns the square root of x
  • Math.max(x, y, z, …, n) – Returns the number with the highest value
  • Math.min(x, y, z, …, n) – Returns the number with the lowest value

Example:
Math.round((field_1 + field_2 – field_3)*100)/100 – will return the calculation rounded to hundredths

How can I round the calculated result to 2 decimal digits?

For examle, we need to round the result of formula = field_1 + field_2 – field_3

  • 1 way. Use only function Math.round:
    Math.round((field_1 + field_2 – field_3)*100)/100
  • 2 way. Use function .toFixed(2):
    (field_1 + field_2 – field_3).toFixed(2)
Where can I publish a form?

You can publish the forms into pages, posts and widget. The shortcode can be also placed into the template.
