Why checks use "XX/100"
Writing cents as a fraction of 100 rather than spelling them out is the long-standing US convention for checks — it leaves no room for ambiguity between the written amount and the numeric one in the box, and it's what banks expect to see. Some contracts and legal documents ask for the fully spelled-out form instead; this calculator supports both.
