isNatural :: JSString -> Bool Source
Returns whether the JSString represents a natural number at base 10 (including 0)
readInt :: JSString -> Int Source
Convert a JSString to an Int, throwing an exception if it cannot be converted. Leading spaces and trailing non-digit characters are not allowed.
readIntMaybe :: JSString -> Maybe Int Source
Convert a JSString to an Int, returning Nothing if it cannot be converted. Leading spaces and trailing non-digit characters are not allowed.
lenientReadInt :: JSString -> Int Source
Convert a JSString to an Int, throwing an exception if it cannot be converted. Leading spaces are allowed. The function ignores trailing non-digit characters.
readInt64Maybe :: JSString -> Maybe Int64 Source
readWord64 :: JSString -> Word64 Source
readWord64Maybe :: JSString -> Maybe Word64 Source
readDouble :: JSString -> Double Source
Convert a JSString to an Int, throwing an exception if it cannot be converted. Leading spaces are allowed. The function ignores trailing non-digit characters.
readDoubleMaybe :: JSString -> Maybe Double Source
Convert a JSString to a Double, returning Nothing if it cannot be converted. Leading spaces are allowed. The function ignores trailing non-digit characters.
readInteger :: JSString -> Integer Source
