Float to Fixed Point in FPGA

You could use this javascript form I created

http://davidcastells.blogspot.com.es/2012/07/floating-point-to-fixed-point-online.html

...and use the binary value

if you are using 16 bits for integer part, and 16 bits for the decimal

0.7071 becomes "00000000000000001011010100000100"

and 0.2487 becomes "00000000000000000011111110101010"

you can play with other bit width representations
