calculateRawAmount does not work with e-notation

Lines 114 to 121 in c2453bc

	export const calculateRawAmount = (amount: number, decimals: number): bigint => {
	const [integerPart, fractionalPart = ''] = amount.toString().split('.');
	// Ensure the fractional part has enough digits
	const paddedFraction = fractionalPart.padEnd(decimals, '0').slice(0, decimals);
	return BigInt(integerPart + paddedFraction);
	};

This code convets number to a string and then slices the string by the dot. Works well for regular numbers, but not for very small ones, for example 0.000000001 convers by js to 1e-9.

The easiest and most reliable way to convert any number in any notation is by Intl.NumberFormat:

Intl.NumberFormat('en-US', { maximumFractionDigits: decimals || 36 }).format(Number(value)) will return string of value (with e-notation or not) without loss in precision, but it may be slower than finding index of e and then converting via slicing and concatenating. In any case, e-notation should be handled if developer prefers amount over rawAmount for ton assets.
