When viewing the same data in FR2 and FR5, the 14th decimal place increases by 1 in Empower - WKB93124

SYMPTOMS

• When reviewing data, the 14th decimal place (15th significant figure) increases by 1 in Empower
• Viewing the same data in Empower 3 FR2 and FR5

ENVIRONMENT

• Empower 3 Feature Release 5

CAUSE

This is a display feature in FR5 due to software compiler. Please see below for additional information.

FIX or WORKAROUND

None

ADDITIONAL INFORMATION

Please see the EMP 3 FR5 release notes and INFEMP-6691 under “Numerical Differences” on page 17 of the PDF. 

The information is also pasted below:

"When you use Empower 3 Feature Release 5 software, some numbers may display differently than in previous versions of Empower. These number display changes may appear in Empower 3 Feature Release 5 regardless of the Empower version in which the values were calculated. The slight differences are due to the software compiler used with Empower 3 Feature Release 5. 

Empower 3 Feature Release 5 software is compiled using an updated compiler within Microsoft’s current development tool suite. The updated compiler formats floating point numbers for display with greater accuracy than the previous compiler. The updated compiler affects only how Empower 3 Feature Release 5 software formats floating point numbers for display. It does not affect numeric calculations. Additionally, Empower 3 Feature Release 5 displays floating point numbers in scientific notation with a 3-digit exponent instead of a 2-digit exponent. 

When testing Empower 3 Feature Release 5, out of the thousands of numbers tested, only four numbers differed from previous versions of Empower. All four of the differences occurred at the 15th significant figure. For each of these four numbers, the last displayed digit was rounded up or down by one. This information addresses INFEMP-6691. "

NOTE: The compiler version impacts how data is managed between various data formats and string presentations in Empower. In previous version rounding was also performed by the compiler before converting to strings. This rounding does not occur in FR5.
