Difference between Pricescope HCA and Diamond-Cut HCA

[srgraves]

Why does the HCA at http://www.diamond-cut.com.au/holloway_cut_adviser.htm round tables down (for grid displayed), while the HCA at https://www.pricescope.com/cutadviser.asp round tables up?

For example:

AGS Ideal 0
Carat weight: 1.01
Cut: Ideal
Color: F
Clarity: SI1
Depth %: 62.3%
Table %: 54.5%
Crown: 35.7
Pavillion: 40.6
Symmetry: Ideal
Polish: Ideal
Girdle: Thin to medium
Culet: None
Fluorescence: Negligible
Measurements: 6.46x6.41x4.01 mm
HCA Total Visual Performance 1.5 - Excellent
within FIC range
Factor Grade
Light Return Excellent
Fire Excellent
Scintillation Excellent
Spread Very Good

On the Diamond-Cut HCA it plots it on the 54 table grid while on the Pricescope HCA it plots it on the 55 table grid? Gosh, is there anyone else more OCD than me? By the way I had Thom Underwood appraise this FIC and he was quite impressed.

Thanks,
Scott

Indeed

Thanks for the heads-up, Srgraves!

Small difference in the script causes this problem. Math.Round() rounds 54.5 down to 54.0

I'm going to fix it now...
