fnumber (a # -- r ? ) convert the specified string by a and # to float r, on success flag is true >float (a # -- r ? ) convert the specified string by a and # to float r, on success flag is true (more robust)

f. ( r -- ) display, with a trailing space, the floating-point number r in fixed-point notation fe. ( r -- ) display, with a trailing space, the floating-point number r in engineering notation fs. ( r -- ) display, with a trailing space, the floating-point number r in scientific notation precision ( -- u ) return the number of significant digits currently used by F., FE., or FS. as u set-precision ( u -- ) set the number of significant digits currently used by F., FE., or FS. to u

Fixed-Point Words

d+ ( d1 d2 -- d3 ) add d1 to d2 giving the sum d3 d- ( d1 d2 -- d3 ) subtract d2 from d1, giving d3 fx* ( d1 d2 -- d3 ) multiply d1 by d2 giving d3
