How to force csh to not use floating point?

Hi,

I'm using csh, grep, and awk to sum up the third field from a file.
Unfortunately, this results in a very large number and csh
creates a floating point value such as 3.11745e+06.
I was hoping to get 3117450.

I get this error when I run this portion of the csh script and I suspect the variable "dpram" gets the floating point value and "bc" or "sed" cannot handle this.

(standard_in) 1: parse error

CSH program test.csh: (shortened version)
#!/bin/csh
foreach fn ($1/*_gates_power.rpt)
set dpram = `grep "^DPRAM_" $fn | grep -v " 0.0 " | awk '{x += $3 }; END {print x}' | bc | sed 's/[.].//' `
echo $dpram
end

Input file : xyz_gates_power.rpt

DPRAM_2048X8 12 4888.00 1396415.76
DPRAM_2048X8_worst_lib 1 0.0 134956.76

The purpose of " bc | sed 's/[.].//' " is to convert decimal value to integer.
37.0 to 37

Unix cmd-line : unix> test.csh reports

Thanks,

David

Floating Point Division

Does anyone have a simple way of doing floating point ("fp") division? For example, if I divide 3 by 5, I can get 0.6. The built-in calc (`bc`) will perform fp multiplication, but not division, at least not straight-up (i.e., starting bc and just typing in 3/5). I am trying to do this using...
