The format method obviously rounds the input if there is no fraction digits allowed.

maximumFractionDigits: 0,

Rounding is driven by midpoint rule away from zero.

console.log(new Intl.NumberFormat("en", { minimumIntegerDigits: 2, maximumFractionDigits: 0, minimumFractionDigits: 0 }).format(0.49));
"00"
console.log(new Intl.NumberFormat("en", { minimumIntegerDigits: 2, maximumFractionDigits: 0, minimumFractionDigits: 0 }).format(0.5));
"01"

Possibly you want to truncate the decimal part.

Math.trunc()

You can use Math.floor before doing the format. Like this:

console.log(new Intl.NumberFormat("en", { minimumIntegerDigits: 2, maximumFractionDigits: 0, minimumFractionDigits: 0 }).format(Math.floor(0.8)));
