Detailed Description

class com::wombat::mama::MamaPricePrecision;

The MamaPricePrecision class determines how decimals are represented for the price. PRECISION_10 - PRECISION_10000000000 represent decimal places. PRECISION_DIV_2, _4, etc, represent fraction 1/2’s ,1/4’s etc.

TICK_32, HALF_32 are for feeds that send prices in 1/32’s and half 1/32’s.
