Amount slippage computation

[peterjah]

Hello,
I'm trying to understand how AmountMin are computed from allowed slippage here:

joe-sdks/packages/v2/src/v2entities/pair.ts

Line 444 in 1a0d34c

const amountXMin = new Fraction(ONE)

    const amountXMin = new Fraction(ONE)
      .add(amountSlippage)
      .invert()
      .multiply(amountX).quotient

for allowed slippage of 100%, it would gives a amountXMin = amountX / 2
Is it intended ? should amountXMin be 0 in that case ?

Intuitively i would do like this:
const amountXMin = (new Fraction(amountX).multiply(new Fraction(1n).subtract(amountSlippage))).quotient;
