<number>
Methods in this pseudo-class can be executed on arbitrary precision number values.
Definition Pseudo_QC_Number.dox.h:6

<number>::prec
int prec()
Returns the precision of the current number.

<number>::format
string format(int prec=2, string decimal_sep=".", string thousands_sep="")
Returns a formatted string of the number according to format arguments.

<number>::sign
int sign()
Returns -1 if the number is negative, 0 if it is zero, or 1 if it is positive.

<number>::val
bool val()
Returns True if the number is non-zero, False if zero.

<number>::abs
number abs()
Returns the absolute value of the number.

<number>::strp
bool strp()
Returns True because number values can be converted to strings.

<number>::nanp
bool nanp()
Returns True if the number is NaN (not a number)

<number>::infp
bool infp()
Returns True if the number is infinity (+ or -)

<number>::format
string format(string fmt)
Returns a formatted string of the number according to the format argument.

<number>::intp
bool intp()
Returns True because number values can be converted to integers.

<number>::typeCode
int typeCode()
Returns Qore::NT_NUMBER.

<number>::toBase
string toBase(int base=10)
Converts the number to a different base (and returns it as a string).

<number>::toString
string toString(int fmt)
Returns the string representation of the number according to the format argument.

<value>
Methods in this pseudo-class are available to be executed on any value type (even NOTHING); this is t...
