How to control digit numbers after the decimal point when writing values for a calibrated parameter? #23

Open WatershedFlow opened 3 years ago

WatershedFlow commented 3 years ago

When I use hydroPSO, I found that I cannot control digit numbers after the decimal point when writing a new value for the calibration parameter. For example, hydroPSO would write one value as 32.045634, while I only want 32.04. How to fix this, Mauricio?

Dear Kangsheng,

Thanks for your interest in hydroPSO.

If you are using the 'hydromod' function you might control the amount of decimal digits in the 'ParameterFiles.txt' file, in the 'DecimalPlaces' column. See page 25 in the hydroPSO vignette for SWAT2005 and MODFLOW2005: https://www.rforge.net/hydroPSO/files/hydroPSO_vignette.pdf

Kind regards

Mauricio

I did this as showed the following line (I also attach a file for clarity)

TOPSOIL SCCReek.rvp 54 27 39 2

But, the value is still, such as 20.654709, not 20.65.

Maybe something is wrong. Thanks for your help.
