WebIf we want to display floating point numbers we need to use %f. We can specify the number of decimal places we want like this: %0.2f. The 2 here indicates that we want to keep only two decimal places. Here is an example: score = 78.5431 puts "The average is %0.2f" % [score] Output => The average is 78.54 Remember that the number will be rounded up.

For float f and real number r, these expressions are equivalent:
WebRuby looks up the / operator in the first operand, in this case an integer, and then calls the function with the second operand, also an integer. Thus Ruby assumes you want integer division. The solution is to make one of the operators a float, this can be done in at least two ways: 5 / 2.0 or 5 / 2.to_f Share Improve this answer Follow
