[Closed] 16bit float

this is the code to convert it in c#
UInt16 mantissa = (UInt16)(value & 0x3FF); (extracts the last 10 bits)
Byte exponent = (Byte)((value >> 10) & 0x1F); (extracts bits 2 to 6)
Byte sign = (Byte)(value >> 15); (extracts first bit)
can anyone convert this to max script

here’s the script for extracting the sign, exponent and fraction from a 32 bit float in maxscript. dunno how to get the mantisa though.

  (
  	fl = 6.5
  	fli = bit.floatasint fl
  	sign = bit.get fli 32
  	-- bit.hexasint "7f800000" = 2139095040; 
  	exponent = bit.shift (bit.and fli 2139095040) -23
  	-- bit.hexasint "7fffff" = 8388607
  	fraction = (bit.and fli 8388607) 
  	--fraction is displayed as hex, user prefrence really 
  	format "sign = %, exponent = %, fraction (in hex) = %
" (sign) (exponent-127) (bit.intashex fraction)
  )

Edit*: here’s the code for reading a 16 bit integer from a binary file and converting it to a 32 bit float

 (	
 	fn convertTo32 input16 = 
 	(
 		inputAsInt = input16
 		sign = bit.get inputAsInt 16
 		exponent = (bit.shift (bit.and inputAsInt (bit.hexasint "7C00")) -10) as integer - 16
 		fraction = bit.and inputAsInt (bit.hexasint "03FF")
 		if sign==true then sign = 1 else sign = 0
 		exponentF = exponent + 127
 		--Ouput 32 bit integer representing a 32 bit float
 		outputAsFloat = bit.or (bit.or (bit.shift fraction 13) (bit.shift exponentF 23)) (bit.shift sign 31)
 		--Output Check	
 		return bit.intasfloat outputasfloat
 	)
 	
 	filename  = createfile "D:\\myBin.bin" 
 	filename = fopen "D:\\myBin.bin" "wb"
 	writeshort filename 18080 --16bit float representation of 3.3125
 	fclose filename
 	
 	filename = fopen "D:\\myBin.bin" "rb"
 	input16 = readshort filename
 	fclose filename
 	
 	convertTo32 input16
 )

cheers!
