Numeric Functions

All numeric functions return a numeric result and only accept numeric arguments.

$FABS(n)

Absolute value Returns: Numeric

This function returns the absolute value of the argument n.

$FCEIL(n)

Round up to whole number Returns: Numeric

This function returns the smallest whole number that is greater than or equal to n.

$FFLOOR(n)

Round down to whole number Returns: Numeric

This function returns the largest whole number that is less than or equal to n.

$FFRAC(n)

Fractional portion Returns: Numeric

This function returns the fractional portion of the argument n.

$FINT(n)

Truncation to whole number Returns: Numeric

This function returns the integer portion (i.e., whole number) of the argument n.

$FMAX(n1[,n2[,…]])

Largest value Returns: Numeric

This function returns the argument having the largest value from the list of numeric arguments specified. At least two arguments should be specified.

$FMIN(n1[,n2[,…]])

Smallest value Returns: Numeric

This function returns the argument having the smallest value from the list of numeric arguments specified. At least two arguments should be specified.

$FMOD(n1,n2)

Remainder Returns: Numeric

This function returns the remainder of the quotient n1/n2. $FMOD generates an error if n2 is zero.

$FNINT(n)

Nearest whole number Returns: Numeric

This function returns the nearest whole number of the argument as $FINT(n+.5*$FSIGN(n)).

$FSIGN(n)

Sign Returns: Numeric

This function returns –1 if n is negative, 0 (zero) if n is zero and +1 if n is positive.
