Ceil (100.12): ", Math.ceil (100.12) print" Math.ceil (100.72): ", Math.ceil (100.72) print" Math.ceil (119L): ", Math.ceil (119L) print "Math.ceil (Math.PI):", Math.ceil (Math.PI)

When we run the above program, it produces the following results:


1 2 3 4 5 Math.ceil ( -45.17): -45.0 Math.ceil (100.12): 101.0 Math.ceil (100.72): 101.0 Math.ceil (119L): 119.0 Math.ceil (Math.PI): 4.0
