Float textures

Has anybody used float textures to store data?
Is the A16B16G16R16F the float texture format and how do I write the float value?


how do you mean store data? you can write into a float texture with a shader…

well I mean store float data into a texture … I need to store large arrays and text is really unhandy for this, especially when you need to look up certain items and you know where they are. text becomes really hard to handle and navigate. v4 with 32bit memory address space is very limited too.

how would I write - and read out such a texture with a shader?
