formatFloat

Formats a number with thousand separators on the integer part while preserving the original decimal digits (no rounding or padding).

import { formatFloat } from '@swapped/connect-sdk/format'

formatFloat(1000)
// "1,000"          — no fractional part → none added

formatFloat(1234.56)
// "1,234.56"

formatFloat(1.2345)
// "1.2345"         — keeps all original fractional digits

formatFloat(0.001)
// "0.001"

formatFloat(1_234_567.89)
// "1,234,567.89"

formatFloat(-0.5)
// "-0.5"           — sign is kept for values between -1 and 0

Scientific notation is expanded (1e-7 → 0.0000001). NaN and Infinity return ''.

Built on formatInteger for the integer part.
