Function: formatBig()

function formatBig(value: number | BigNumber, precision?: number): string;

Render a BigNumber (or JS number) to a string at precision significant digits.

Parameters

Parameter	Type	Default value
`value`	\| `number` \| `BigNumber`	`undefined`
`precision`	`number`	`DEFAULT_PRECISION`

string

An EXACT INTEGER is rendered in full fixed notation regardless of precision: an integer carries no fractional precision to lose, so 8000000000000 stays 8000000000000 rather than being truncated to 8e+12. (Bounded at 30 digits to avoid pathological astronomically-large integers printing thousands of characters; beyond that, sig-fig exponential is used.)
Non-integers are rendered at precision significant digits (default 8), stripping trailing zeros — avoiding the toPrecision artifact that mangled safe values, while still giving the caller control over how many digits they want (raise precision for more).
Exact zero renders as '0'. (Genuinely tiny values like 2.54e-5 are preserved, NOT snapped.)
