+// Quantity is a fixed-point representation of a number.
+// It provides convenient marshaling/unmarshaling in JSON and YAML,
+// in addition to String() and Int64() accessors.
+//
+// The serialization format is:
+//
+// <quantity> ::= <signedNumber><suffix>
+// (Note that <suffix> may be empty, from the "" case in <decimalSI>.)
+// <digit> ::= 0 | 1 | ... | 9
+// <digits> ::= <digit> | <digit><digits>
+// <number> ::= <digits> | <digits>.<digits> | <digits>. | .<digits>
+// <sign> ::= "+" | "-"
+// <signedNumber> ::= <number> | <sign><number>
+// <suffix> ::= <binarySI> | <decimalExponent> | <decimalSI>
+// <binarySI> ::= Ki | Mi | Gi | Ti | Pi | Ei
+// (International System of units; See: http://physics.nist.gov/cuu/Units/binary.html)
+// <decimalSI> ::= m | "" | k | M | G | T | P | E
+// (Note that 1024 = 1Ki but 1000 = 1k; I didn't choose the capitalization.)
+// <decimalExponent> ::= "e" <signedNumber> | "E" <signedNumber>
+//
+// No matter which of the three exponent forms is used, no quantity may represent
+// a number greater than 2^63-1 in magnitude, nor may it have more than 3 decimal
+// places. Numbers larger or more precise will be capped or rounded up.
+// (E.g.: 0.1m will rounded up to 1m.)
+// This may be extended in the future if we require larger or smaller quantities.
+//
+// When a Quantity is parsed from a string, it will remember the type of suffix
+// it had, and will use the same type again when it is serialized.
+//
+// Before serializing, Quantity will be put in "canonical form".
+// This means that Exponent/suffix will be adjusted up or down (with a
+// corresponding increase or decrease in Mantissa) such that:
+// a. No precision is lost
+// b. No fractional digits will be emitted
+// c. The exponent (or suffix) is as large as possible.
+// The sign will be omitted unless the number is negative.
+//
+// Examples:
+// 1.5 will be serialized as "1500m"
+// 1.5Gi will be serialized as "1536Mi"
+//
+// Note that the quantity will NEVER be internally represented by a
+// floating point number. That is the whole point of this exercise.
+//
+// Non-canonical values will still parse as long as they are well formed,
+// but will be re-emitted in their canonical form. (So always use canonical
+// form, or don't diff.)
+//
+// This format is intended to make it difficult to use these numbers without
+// writing some sort of special handling code in the hopes that that will
+// cause implementors to also use a fixed point implementation.

+// Quantity is a fixed-point representation of a number.
+// It provides convenient marshaling/unmarshaling in JSON and YAML,
+// in addition to String() and Int64() accessors.
+//
+// The serialization format is:
+//
+// <quantity> ::= <signedNumber><suffix>
+// (Note that <suffix> may be empty, from the "" case in <decimalSI>.)
+// <digit> ::= 0 | 1 | ... | 9
+// <digits> ::= <digit> | <digit><digits>
+// <number> ::= <digits> | <digits>.<digits> | <digits>. | .<digits>
+// <sign> ::= "+" | "-"
+// <signedNumber> ::= <number> | <sign><number>
+// <suffix> ::= <binarySI> | <decimalExponent> | <decimalSI>
+// <binarySI> ::= Ki | Mi | Gi | Ti | Pi | Ei
+// (International System of units; See: http://physics.nist.gov/cuu/Units/binary.html)
+// <decimalSI> ::= m | "" | k | M | G | T | P | E
+// (Note that 1024 = 1Ki but 1000 = 1k; I didn't choose the capitalization.)
+// <decimalExponent> ::= "e" <signedNumber> | "E" <signedNumber>
+//
+// No matter which of the three exponent forms is used, no quantity may represent
+// a number greater than 2^63-1 in magnitude, nor may it have more than 3 decimal
+// places. Numbers larger or more precise will be capped or rounded up.
+// (E.g.: 0.1m will rounded up to 1m.)
+// This may be extended in the future if we require larger or smaller quantities.
+//
+// When a Quantity is parsed from a string, it will remember the type of suffix
+// it had, and will use the same type again when it is serialized.
+//
+// Before serializing, Quantity will be put in "canonical form".
+// This means that Exponent/suffix will be adjusted up or down (with a
+// corresponding increase or decrease in Mantissa) such that:
+// a. No precision is lost
+// b. No fractional digits will be emitted
+// c. The exponent (or suffix) is as large as possible.
+// The sign will be omitted unless the number is negative.
+//
+// Examples:
+// 1.5 will be serialized as "1500m"
+// 1.5Gi will be serialized as "1536Mi"
+//
+// Note that the quantity will NEVER be internally represented by a
+// floating point number. That is the whole point of this exercise.
+//
+// Non-canonical values will still parse as long as they are well formed,
+// but will be re-emitted in their canonical form. (So always use canonical
+// form, or don't diff.)
+//
+// This format is intended to make it difficult to use these numbers without
+// writing some sort of special handling code in the hopes that that will
+// cause implementors to also use a fixed point implementation.
