Converts a character string containing an integer number into the corresponding integer form.

Required Arguments

STRING — Character string containing an integer number.   (Input)

NUMBER — The integer equivalent of STRING.   (Output)

FORTRAN 90 Interface

Generic:                              CALL CVTSI (STRING, NUMBER)

Specific:                             The specific interface name is CVTSI.

FORTRAN 77 Interface

Single:                                CALL CVTSI (STRING, NUMBER)

Description

Routine CVTSI converts a character string containing an integer to an INTEGER variable. Leading and trailing blanks in the string are ignored. If the string contains something other than an integer, a terminal error is issued. If the string contains an integer larger than can be represented by an INTEGER variable as determined from routine IMACH (see the Reference Material), a terminal error is issued.

Example

The string “12345” is converted to an INTEGER variable.

 

      USE CVTSI_INT

      USE UMACH_INT

 

      IMPLICIT   NONE

      INTEGER    NOUT, NUMBER

      CHARACTER  STRING*10

!

      DATA STRING/'12345'/

!

      CALL CVTSI (STRING, NUMBER)

!

      CALL UMACH (2, NOUT)

      WRITE (NOUT,*) 'NUMBER = ', NUMBER

      END

Output

 

NUMBER =   12345
