Standard ML - Code Examples

Code Examples

Snippets of SML code are most easily studied by entering them into a "top-level", also known as a read-eval-print loop. This is an interactive session that prints the inferred types of resulting or defined expressions. Many SML implementations provide an interactive top-level, including SML/NJ:

Code can then be entered at the "-" prompt. For example, to calculate 1+2*3:

- 1 + 2 * 3; val it = 7 : int

The top-level infers the type of the expression to be "int" and gives the result "7".

Famous quotes containing the words code and/or examples:

    “Acknowledge your will and speak to us all, “This alone is what I will to be!” Hang your own penal code up above you: we want to be its enforcers!”
    —Friedrich Nietzsche (1844–1900)

    “In the examples that I here bring in of what I have [read], heard, done or said, I have refrained from daring to alter even the smallest and most indifferent circumstances. My conscience falsifies not an iota; for my knowledge I cannot answer.”
    —Michel de Montaigne (1533–1592)
