public pure subroutine decToInt128(input, output, error, startpos, endpos)
Parse the input
string as a signed decimal integer string to an int128 value.
This subroutine ignores leading and trailing whitespaces.
This subroutine considers an error to has occurred:
1. If the input
string only contains empty spaces.
2. If the input
string have a length of zero.
3. If the value for either the startpos
or endpos
arguments is incorrect.
4. If the input
string contains a value that is smaller than the min value of the int128 data type or larger then the max value of the int128 data type.
5. If the input
string is not a valid signed decimal integer string.
