Format change in exportmeasure utility

Hi,

I have a real measure mstst(intx loc) which have data as below

1001,0.42980035386604

I want to export this value as below into mstst1.casv.ovr file

1001,0.42

Then I want load this data to string measure mstst1(intx loc) with loadmeasure

I have a script where I put a variable as below

exp_data_type_real="%0.2f"

export_meas_spec="${exp_measure}.precision(0.01).format(${exp_data_type_real})

then run teh below command in in script

exportMeasure -d ${RDF_DOMAIN} -out mstst1.csv.ovr -intx $loc -meas mstst -processes 2

but it gave me data in mstst1.csv.ovr as below
