CDATE

Current date.

CTIME

Current time.

negative) date d1. The format for d1

 

is set in the TIME/SET menu.

DDAYS(d1:d2:cal)

x!; factorial of a positive integer.

FLOW(CFLO-listname:flow#)

Value of the specified cash flow.

FP(x)

Fractional part of x.

G(x)

Returns (Get) the value of the variable.
