public sealed class PricingExpression : IMessage<PricingExpression>, IEquatable<PricingExpression>, IDeepCloneable<PricingExpression>, IBufferMessage, IMessage
Reference documentation and code samples for the Google Cloud Billing v1 API class PricingExpression.
Expresses a mathematical pricing formula. For Example:-
public double BaseUnitConversionFactor { get; set; }
Conversion factor for converting from price per usage_unit to price per
base_unit, and start_usage_amount to start_usage_amount in base_unit.
unit_price / base_unit_conversion_factor = price per base_unit.
start_usage_amount * base_unit_conversion_factor = start_usage_amount in
base_unit.
The recommended quantity of units for displaying pricing info. When
displaying pricing info it is recommended to display:
(unit_price * display_quantity) per display_quantity usage_unit.
This field does not affect the pricing formula and is for display purposes
only.
Example: If the unit_price is "0.0001 USD", the usage_unit is "GB" and
the display_quantity is "1000" then the recommended way of displaying the
pricing info is "0.10 USD per 1000 GB"
public RepeatedField<PricingExpression.Types.TierRate> TieredRates { get; }
The list of tiered rates for this pricing. The total cost is computed by
applying each of the tiered rates on usage. This repeated list is sorted
by ascending order of start_usage_amount.
