/**
* num cvi int or string cvi int
*
* takes an integer, real, or string and produces an
* integer result. If the operand is an integer, cvi
* simply returns it. If the operand is a real number,
* it truncates any fractional part (that is, rounds
* it toward 0) and converts it to an integer.
* If the operand is a string, cvi invokes the equivalent
* of the token operator to interpret the characters
* of the string as a number according to the PostScript
* syntax rules. If that number is a real number, cvi converts
* it to an integer.
* A rangecheck error occurs if a real number is too
* large to convert to an integer.
*
* errors: invalidaccess, rangecheck, stackunderflow,
* syntaxError, typecheck,
