XTCE12 — Valid sizeInBits values for encoding="MILSTD_1750A"

Open Closed All
  • Key: XTCE12-17
  • Legacy Issue Number: 19415
  • Status: closed  
  • Source: Jacobs Technology, Inc. ( Robert Goodwin)
  • Summary:

    The XTCE schema currently defines the following three legal values for sizeInBits in the FloatDataEncodingType complex type: 32, 64, 128. These legal values are correct if the encoding attribute is “IEEE754_1985”; but for encoding=”MILSTD_1750A”, the legal values should be 32 (single precision) and 48 (extended precision). Reference sections 4.1.5 and 4.1.6 of the MIL-STD-1750A specification (http://www.xgc.com/manuals/m1750-ada/m1750/book1.html). Need to add XTCE support for sizeInBits=48 when encoding=”MILSTD_1750A”.
