DoubleRange

The DoubleRange dictionary is used to define a range of permitted double-precision floating-point values for a property, with either or both a maximum and minimum value specified. The ConstrainDouble dictionary is based on this, augmenting it to support exact and ideal values as well.

Properties

max

A floating-point value specifying the largest permissible value of the property it describes.

min

A floating-point value specifying the smallest permissible value of the property it describes.

The specified min and/or and max values are required. If no match can be found that is within the given range, an error will occur.
