Precision Management

Choosing Precision Levels

pub const BPS_PRECISION: usize = 4;       // Basis points: 10,000 = 100%
pub const BPS: u64 = 10_000;

pub const PPM_PRECISION: usize = 6;       // Parts per million: 1,000,000 = 100%
pub const PPM: u64 = 1_000_000;

pub const WAD_PRECISION: usize = 18;      // Standard token decimals: 1e18 = 1.0
pub const WAD: u128 = 1_000_000_000_000_000_000;
