mod

Return the modulus after division

Syntax

y = mod[value, by]

Attributes

• value - the number to be divided
• by - the number by which to divide value

Description

Modulo division calculates the modulus (the remainder) after dividing value by by. If value is a set of size N, then by can either be a scalar or another set of size N.

Examples

Keeps the value of an angle between the range [π, -π]:

search
  value = 30
  angle = mod[value, by: 2 * pi[]]
  pi2pi = if angle > pi[] then angle - 2 * pi[]
          if angle < pi[] * -1 then angle + 2 * pi[]
          else angle
        
bind @view
  [#value | value: "{{value}} -> {{pi2pi}}"]
