Winter Cardinal UI - v0.457.0 / DScalarExpression

Class: DScalarExpression

Parser and evaluator of the scalar expressions like 100% - 50s.

Literals

• x%: 0.01 * x * parent value
• xs: 0.01 * x * self value
• xp: 0.01 * x * padding value
• xc: 0.01 * x * current value

Operators

• +
• -
• *
• /
• ( and )

Functions

• min( a, b, … )
• max( a, b, … )

Examples

• 90%: 0.9 * parent value
• 50s: 0.5 * self value
• 90% - 50s: 0.9 * parent value - 0.5 * self value
• 90% - (50s + 100) * 2: 0.9 * parent value - ( 0.5 * self value + 100 ) * 2
