Utility tools under Linux--calculators 1. BC Instruction addition, 4. BC Instruction Division (advanced), shown, 10/3 is 3, because we do not specify a decimal point after a few, the default is taken to the integer part, and 10/100 is zero, the same reason, only to take the integer 0 part. Use the "scale=[number" command to specify a few points after the decimal point:The BC Command calculates the remainder, 6. BC Command Count index, 87. How to exit the calculatorSince
