( "∞" | "π" | digit+ ( "." digit+ )? ) digit = "0" | "1" | "2" | "3" | "4" | "5" | "6" | "7" | "8" | "9" -The digits or arabic numerals correspond to the numbers from 0 to 9 in the conventional way (also, each corresponds to its code point value minus 48). A sequence of digits gives a natural number by evaluating it in base 10: the number is 0 for an empty sequence, and otherwise the last digit's numerical value plus ten times the number obtained from the remaining digits. The symbol `∞` indicates infinity and `π` indicates the ratio [pi](https://en.wikipedia.org/wiki/Pi_(mathematics)) of a circle's circumference to its diameter (or, for modern mathematicians, the smallest positive real number at which the function `{⋆0j1×𝕩}` attains a real part of 0). The [high minus](https://aplwiki.com/wiki/High_minus) symbol `¯` indicates that the number containing it is to be negated. +The digits or arabic numerals correspond to the numbers from 0 to 9 in the conventional way (also, each corresponds to its code point value minus 48).

The symbol `∞` indicates infinity and `π` indicates the ratio [pi](https://en.wikipedia.org/wiki/Pi_(mathematics)) of a circle's circumference to its diameter (or, for modern mathematicians, the smallest positive real number at which the function `{⋆0i1×𝕩}` attains a real part of 0). The [high minus](https://aplwiki.com/wiki/High_minus) symbol `¯` indicates that the number containing it is to be negated. When an exponent is provided (with `e` or `E`), the corresponding mantissa is multiplied by ten to that power, giving the value `mantissa×10⋆exponent`. If a second component is present (using `i` or `I`), that component's value is multiplied by the [imaginary unit](https://en.wikipedia.org/wiki/Imaginary_unit) *i* and added to the first component; otherwise the value is the first component's value without modification. If complex numbers are not supported, then `i` should not be allowed in numeric literals, even when followed by 0. |
