Detailed Description

Convert an FXY value from its six character representation to its bit-wise (integer) representation.

Definition in file ifxy.f.

Function/Subroutine Documentation

function ifxy

(

character*6

ADSC

)

This function converts an FXY value from its 6 character representation to its bit-wise (integer) representation.

Author

Date

1994-01-06

Parameters

[in]

ADSC

– character*6: FXY value

Returns

ifxy – integer: Bit-wise representation of FXY value

Remarks

Per the official WMO BUFR regulations, an FXY value can be represented as a bit-wise integer in 16 bits, ordered from left (most significant) to right (least significant), and where the F value occupies the first 2 bits, the X value occupies the next 6 bits, and the Y value occupies the last 8 bits.

For example, if ADSC = '063022'

   F |     X     |      Y
   0 |     63    |      22
  0 0 1 1 1 1 1 1 0 0 0 1 0 1 1 0

then the corresponding ifxy

  = ( 2**13 + 2**12 + 2**11 + 2**10 + 2**9 + 2**8 +
      2**4 + 2**2 + 2**1 )

  = 16150
