SilMinds DecTool Parser-Coder performs two main functions: Parsing and Coding. It codes from/to Densely Packed Decimal numbers in Hex/Binary format to/from the triplet format:
(−1) sign × 10^exponent × significand
Furthermore, you can choose the rounding mode out of five different modes. You can use the tool to encode your 16 digits decimal number to a densely packed number in both Hex/Binary formats. In reverse, the tool can decode any Hex/Binary encoded number to its decimal equivalent.
The Parser tool parses the IBM’s IEEE test suite, in addition to Cairo University DFP Test suite. These test-suites contain test cases that target basic formats specified in the IEEE 754-2008 standard. SilMinds DFP Parser-Coder tool parses decimal64 and decimal128 formats for the following operations:
addition(+-)and subtraction, fused multiply-add(*+), square root(√), multiplication(*) and division(/).
Input files should have “.fptest” extension, input files may need renaming. The tool generates three files: ‘cases.silm’, ‘desc.silm’, and ‘result.silm’
1. Cases.silm
The rounding mode and the two operands.Rounding modes are coded as follows:
000 nearest, ties to even
001 nearest, ties away from zero
010 to positive infinity
011 to negative infinity
100 to zero
101 Round-half-up
110 Round-half-down
2. Desc.silm
All the test cases that matches the precision and the operation chosen.
3. Result.silm
The resultant and the flags. The flags are represented in four bits with the following order: inexact invalid overflow underflow
