decimalPlaces leading to loss of data

I'm running a complete array (no missing values) through the decimalPlaces
function and am getting an output array that contains missing values. Is
this correct?

data_all_f = doubletofloat(fdata->$var$)
printVarSummary(data_all_f)
print(num(ismissing(data_all_f)))
printMinMax(data_all_f,True)
data_all = decimalPlaces(data_all_f,2,True)
printVarSummary(data_all)
print(num(ismissing(data_all)))
printMinMax(data_all,True)

Variable: data_all_f
Type: float
Total Size: 116640000 bytes
            29160000 values
Number of Dimensions: 3
Dimensions and sizes: [1800] x [90] x [180]
Coordinates:
Number Of Attributes: 1
  _FillValue : 1e+20
(0) 0
