Items not described here are as in the Standard ML Basis' INTEGER signature.
A local synonym for type int.
An explicit equality function on integers. Equivalent to op=.
A hash function for integers. Returns i itself.
Like specified in the Standard ML Basis, except that underscores are allowed to separate digits. The scan function thus accepts the following formats:
StringCvt.BIN [+~-]?[0-1_]*[0-1][0-1_]*
StringCvt.OCT [+~-]?[0-7_]*[0-7][0-7_]*
StringCvt.DEC [+~-]?[0-9_]*[0-9][0-9_]*
StringCvt.HEX [+~-]?(0x|0X)?[0-9a-fA-F_]*[0-9a-fA-F][0-9a-fA-F_]*
The expression fromString s is equivalent to StringCvt.scanString (scan DEC) s.
