Number and currency expressions

Updated 4 weeks ago by Neil

Number and currency expressions are similar. However, many functions, methods, and operators may not work when evaluating numbers and currencies together.

If you use multiple currency fields, make sure they are the same type. Rating and slider fields can be used as number fields in expressions. 

Example fields

We’ll use these sample fields in the expressions below.

FieldID

Type

Value

num1

Number

10

num2

Number

22.45

cur1

Currency

$10

Number and currency functions

Functions go at the start of the expression.

Rand

Number

Mod

Number or Currency

Shows the remainder when the dividend is divided by the divisor.

If the dividend is a currency, the result is also a currency.

Mod(num1, 3)

Mod(cur1, 3)

1

$1

Min

Number or Currency

Shows the minimum value of a set of numbers.

Min(num1, num2)

10

Max

Number or Currency

Shows the maximum value of a set of numbers.

Max(num1, num2)

22.45

Methods

Methods come after the fieldID and are called up with a dot operator. 

Function

round

Rounds a number up or down.

Add the number of decimal places you want. 

num2.round()

num2.round(1)

roundup

Always rounds a number up.

Add the number of decimal places you want. 

num2.roundup()

num2.roundup(1)

rounddown

Always round a number down.

Add the number of decimal places you want.

num2.rounddown()

num2.rounddown(1)

22

22.4

ceil

Rounds up a number to the nearest unit given.

If no value is given, it is treated as 1.

num2.ceil(5)

25

floor

num2.floor(5)

20

abs

Shows the absolute value of a number.

num2.abs()

22.45

code

Shows the currency code in a text field. 

cur1.code()

USD

Operators

There are five arithmetic operators in Kissflow: 

  • Addition (+)
  • Subtraction (-)
  • Multiplication (*)
  • Division (/)
  • Exponents (^)

Expressions with arithmetic operators can use integers or fields. 

Using operators

Here are all the ways that you can evaluate fields.

value

Converts a currency value to a number value.

cur1.value()

10

Number

Converts a text value to a number.

E.g. the value of text1 is “10”.

Number(text1)

10

Currency

Converts a number value to a specific currency.

Currency(num1, GBP)

£ 10

convert

Converts one currency into another type with a static exchange rate.1 

cur1.convert(.90, “EUR”)
