''fixed height2jumpz(fixed height, fixed gravity)''

===== Description =====
Converts jump height to JumpZ, assuming specified gravity. 

[[:units|Gravity is specified as acceleration, not as sv_gravity units.]]

<note tip>Default gravity is ''1.0''. Use [[GetGravityG]] to retrieve current gravity.</note>

===== Conversion formula =====

''height = 0.5 * jumpz^2 / gravity''

===== Examples =====
<code>
int jumpz = height2jumpz(8.0, 1.0);
print(s:"To jump 8 mapunits high in normal gravity, you need to set JumpZ to ", f:jumpz);
