Convert hex string to decimal number

[anhntsi]

I have to try convert hex string: 0x00000000000000000000000000000000000000000000000a4cc799563c380000 but library return nil.

I was able to duplicate this problem with the following code:

if let x1 = BInt(prefixedNumber: "0x00000000000000000000000000000000000000000000000a4cc799563c380000") {
    print("x1 = ", x1.asString(radix: 16))
} else {
    print("x1 returns nil for BInt(prefixedNumber: \"0x00000000000000000000000000000000000000000000000a4cc799563c380000\", radix:16)")
}
