I'm feeling generous, have some pseudo-code.

+ Code Snippet

Have two variables.
isJumping = 0
and
jumpAmount# = 2.0 (Or another arbitrary amount.
Spacebar makes you jump. (GetRawKeyReleased( 32 ) )

Start of game loop
`If you release the spacebar, start to jump, and set the jump amount. (Higher numbers make you jump faster.
If GetRawKeyReleased( 32 ) Then isJumping = 1 : jumpAmount# = 2.0

If isJumping = 1
  `Subtract 0.25 from the jump amount
   jumpAmount# = jumpAmount# - 0.25 (Or another arbitrary amount)

  `Add the jumpAmount# to the sprites Y Position
   SpriteYPosition = SpriteYPosition + jumpAmount#'
   
  `If the sprite has landed ion the floor
   If SpriteYPosition <= floorHeight
     `stop jumping and reset variables.
      isJumping = 0
      SpriteYPosition = FloorHeight
   EndIf
EndIf
end of game loop
