SassNumber class

A SassScript number.

Numbers can have units. Although there's no literal syntax for it, numbers support scientific-style numerator and denominator units (for example, miles/hour). These are expected to be resolved before being emitted to CSS.

Methods

assertInt([String name ]) int
Returns value as an int, if it's an integer value according to isInt. [...]
assertNoUnits([String name ]) → void
Throws a SassScriptException unless this has no units. [...]

Returns a copy of this number, converted to the units represented by newNumerators and newDenominators. [...]
hasUnit(String unit) bool
Returns whether this has unit as its only unit (and as a numerator).
valueInRange(num min, num max, [ String name ]) num
If value is between min and max, returns it. [...]
valueInUnits(List<String> newNumerators, List<String> newDenominators) num
Returns value, converted to the units represented by newNumerators and newDenominators. [...]
