Tests:

bigint
const precision = 1e8; const bpsPrecision = BigInt(1e4); const a = BigInt('123456'); const b = BigInt('124456'); const c = ((b * bpsPrecision) / a) - bpsPrecision;
decimal.js
const a = new Decimal('123.456'); const b = new Decimal('123.456'); const c = b.div(a).minus(1).mul(1e4)
native (parseFloat int)
const precision = 1e8; const a = Math.trunc(parseFloat('12345.6')); const b = Math.trunc(parseFloat('12445.6')); const c = Math.trunc(((b * 1e4) / a) - 1e4);
native (float)
const precision = 1e8; const a = parseFloat('123.456'); const b = parseFloat('124.456'); const c = ((b * 1e4) / a) - 1e4;
native (int parseInt)
const precision = 1e8; const a = parseInt('12345.6'); const b = parseInt('12445.6'); const c = Math.trunc(((b * 1e4) / a) - 1e4);
