The accuracy of floating-point operations in 'TypeScript'

[Gu-code99]

module: coin-bitcoin example: txBuild.calculateTxSize() ->return { inputAmount, outputAmount, virtualSize, txHex };

virtualSize type is 'Number'(In TypeScript) The type of feePerB is also 'Number' estimateBtcFee = virtualSize * feePerB，When fee is a decimal, there may be precision errors in floating-point operations If virtualSize =350,feePerB=2.2, The actual result should be 770, but the result in ts is 770.00000000001
