binaryToInt64 Subroutine

public pure subroutine binaryToInt64(input, output, error, startpos, endpos)

Parse the input string as bits represented by binary digits to an int64 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 beyond the capacity of the int64 data type.
5. If the input string is not a valid binary string.


Type IntentOptional AttributesName
character(len=*), intent(in) :: input

A string to be parsed as a binary string to an int64 value.

integer(kind=k_int64), intent(out) :: output

An int64 value of the input string if no error has occurred during parsing.

logical, intent(out) :: error

A value of .TRUE. if an error has occurred during parsing, or .FALSE., otherwise.

integer(kind=k_int32), intent(in), optional :: startpos

An int32 value of the position(inclusive) of where to start parsing.

integer(kind=k_int32), intent(in), optional :: endpos

An int32 value of the position(inclusive) of where to end parsing.
