how do I do this conversion from float to uint?

with converting float to uint.

there is an example in shadertoy where a float number representing vertices has been converted to uint.

example of the first 4 vertices:
float -> 1.220701, 1.541015, -0.435112, 1.115182
uint equivalent
uint -> 315732U, 759517524U, 732299537U, 759517524U
