sfk calc "1+2*3" do a simple calculation with mathematical operators +  * /, accepting decimal or 0x hexadecimal input values. options dig[its]=n round result to n digits form also print the formula, tab separated after result sum add values from chain text hex print result as 0x hex value experimental brackets support you may add option bra[ckets] to use formulas with brackets, like sfk calc bra 1.0/(1.01.0/(3+5)*9) however this is an experimental feature. wrong calculations may occur with brackets, on highly complex formulas. therefore:  countercheck the output with an alternate calculator before using a command repeatedly.  if you really find formulas that calculate wrong, supply samples in the sfk forum. chaining support can use chain input data as #text within formula. web reference http://stahlworks.com/sfkcalc examples sfk calc "1.0+2.5*3.5" prints 9.75. quotes "" are required with linux but not under windows. sfk echo "1+2*3" +calc "#text*4" calculates 1 + 2*3*4 = 25 sfk echo "1+2*3" +calc "#text" +calc "#text*4" calculates (1+2*3) * 4 = 28 sfk calc hex 0xffffffff+0x1 add two hex values, and show 64bit hex result sfk filt in.txt +calc "#text" form calculate all formulas given in in.txt sfk list size tabform sfk.exe +filt utabform "#col1" +calc "#text/1000" dig=0 show the size of sfk.exe in kbytes, rounded to zero digits after decimal point.
