TOLONG
conversion
binary
Converts a value of primitive type or a BYTE ARRAY into a long value.
The TOLONG function consumes a parameter (BOOLEAN, LONG, DOUBLE, STRING) from the top of the stack and pushes back its conversion to long.
Beware of string inputs with leading zeros: it could be considered as octal. See examples below.

-1.95 TOLONG
// beware of octal/hex representation in strings
"010" TOLONG // return 8
"0x10" TOLONG // returns 16
//byte array
'64' HEX-> TOLONG
'9c' HEX-> TOLONG
123456789 TOHEX HEX-> TOLONG
//Limitations: Be aware of 64 bits limits
2 63 ** //max of a 64bit long
'9223372036854775807' TOLONG //ok
//'9223372036854775808' TOLONG //will fail with an error
92233720368547758000.24 //exceed the 64 bits double
92233720368547758000.24 TOLONG //ooops
