u.
( u --- )
"u-dot". Type the value of the unsigned number on the top of the stack
to the terminal.
u<
( u1 u2 --- tf)
"u-less-than". Perform an unsigned compare of the two unsigned numbers
on the top of the stack. Leave TRUE or FALSE on the stack. (u1<u2).
99000 99900 u<
will return TRUE on the stack. u< is typically used to compare
very large numbers that would be treated as negative by <.
u>
( u1 u2 --- tf)
"u-greater-than". Perform an unsigned compare of the two unsigned
numbers on the top of the stack. Return TRUE if u1 is greater than
u2. Else, return FALSE. (u1>u2).
99000 99900 u>
will return FALSE. u> is typically used for large positive
numbers.
um*
( d1 u1 --- d1*u1 )
"u-m-star". Unsigned mixed length multiply. This is a 32-bit multiply
in Until.
um/mod
( d1 u2 --- rem quot )
"u-m slash mod". Unsigned multiple length division. (d1/u2)
unseal
( --- )
"unseal". Converts a sealed Until source file into 'ASCII' form for
reference. It allows sealed Until applications to be examined
for debugging. unseal is the opposite of seal.
The following line unseals CALC.BIN:
unseal calc.bin
until
( tf --- )
"until". Terminate a begin loop.
: aword begin some_words until ;
until branches back to begin if the value on the stack
is FALSE. TRUE causes the loop to terminate.
