How do I convert a decimal number smaller than 1.0 to hex float?

[CosmoCortney]

Hello,
since I know how to convert any decimal number to hex float (e.g. 1.33333333 = 0x3FAAAAAB) I still struggle with converting a decimal number smaller than 1.0 to hex float (e.g. how do I get 0x3C4CCCCD from 0.0125?)

can anyone help me?
thanks

Maybe this can assist: http://teaching.idallen.com/cst8281/10w/notes/100_ieee754_conversions.txt

It looked pretty thorough to me, but the disclaimer here is that it's 4 in the morning, so I'm rather tired.

this one looks great, thank you

No problem. This assumes of course that the platform you're working with (Wii U? Just a guess) uses standard floats. If you require something for a weird platform like the PS2 which does not use standard floats, then you may need to search further or specify which one.

the info given at the example of -0.5 is sufficient enough for me to understand how to convert a decimal number to any kind of IEEE floats
