int prec()
Returns the precision of the current number.
number number(softnumber n)
Converts the argument to a number value.
bool strp()
Returns True because number values can be converted to strings.
int typeCode()
Returns Qore::NT_NUMBER.
string toBase(int base=10)
Converts the number to a different base (and returns it as a string).
bool infp()
Returns True if the number is infinity (+ or -)
bool intp()
Returns True because number values can be converted to integers.

Definition: Pseudo_QC_Number.dox.h:277
number abs()
Returns the absolute value of the number.
int sign()
Returns -1 if the number is negative, 0 if it is zero, or 1 if it is positive.
const NF_Scientific
for the scientific format (exponential notation)

string format(string fmt)
Returns a formatted string of the number according to the format argument.
string toString()
Returns the string representation of the value; the default is an empty string.
bool val()
Returns True if the number is non-zero, False if zero.
