hi, i'm working on a project where i need to convert a float value to 48 bit hex. Can any one tell me the procedure for this conversion in keil.
these are some samples:
12.00 = 840000000040
21.48 = 8500000AD72B
257.89 = 890000ECF100
Then access the 6 bytes individually and dump as hex.
Be warned, however, that C51 only supports 32-bit floating point numbers.
Ah, yes. There will only be 8 hex characters.
I know that Turbo Pascal had a 6-byte data type implemented in software, besides the 32-bit, 64-bit and 80-bit types supported by the 80x87 instructions.
To create a hex dump using a 6-byte fp format, you will have to decode the bits of the mantissa and exponent and convert from 32-bit to 48-bit format before dumping as hex.
