Instance Method Summary

• #abs(expr : Focus::FloatExpression(T)) : Focus::FloatExpression(T) forall T

  abs - Absolute value

• #abs(expr : Focus::IntExpression(T)) : Focus::IntExpression(T) forall T
• #ceil(expr : Focus::FloatExpression(T)) : Focus::FloatExpression(T) forall T
• #floor(expr : Focus::FloatExpression(T)) : Focus::FloatExpression(T) forall T
• #ln(expr : Focus::NumericExpression) : Focus::FloatExpression(Float64)
