Master numbers in numerology

Master numbers: how the API works it out
The API treats master numbers in two ways, one for each tradition. In the Western numbers on POST /v1/western, master numbers are kept. Each number comes with number, which keeps 11, 22 or 33, and digit, the same number reduced to 1 to 9.
Each part of the date and each word of the name is reduced on its own. So a master number in the middle is not lost. In John Doe's soul urge number, the vowels of Doe add up to 11, and that 11 is kept.
The basis.masters line states the rule. The Indian numbers always end on one digit, so their number field never holds 11, 22 or 33. Instead, the master flag is true when the total is a master number.
It is also true when a step on the way down is one. John Doe's birth date adds up to 33, so his bhagyank (destiny number) is 6 with master true. The spelling Jon Doe adds up to 29, which passes through 11 on the way to 2.
So it gets master true as well. The business name Acme Inc. adds up to 22, which gives 4 with master true. POST /v1/profile shows the flag on the bhagyank and on the name number.
POST /v1/name and POST /v1/business show it for each name. The printed report adds a note beside any Western number that is a master number.
