Maths

Arithmetic

The four operations, plus modulo and power.

Inputs	a, b (numbers)
Outputs	result (number)
Configuration	op: add, sub, mul, div, mod, pow

Comparator

Compares two values and returns a boolean — unlike If, which branches.

Inputs	a, b
Outputs	result (boolean)
Configuration	operator: lt, lte, eq, gte, gt, ne, contains

Use it when the result has to be carried (stored in a variable, sent inside a request body) rather than routed down two ways.

Math

The unary functions and the bounds.

Inputs	a (number), precision (number)
Outputs	result (number)

op	Effect	Fields used
round	Rounds	precision
floor	Rounds down	—
ceil	Rounds up	—
trunc	Truncates	—
abs	Absolute value	—
sign	Sign (-1, 0, 1)	—
sqrt	Square root	—
min	Minimum	b
max	Maximum	b
clamp	Bounds	min, max

For a simple calculation inside a text field, the Handlebars helpers {{add}}, {{multiply}}, {{round}} and {{toFixed}} save you adding a box.
