InitFloat10_F32 (r, mant10, exp10)

Description

Write a float on a buffer location.
buffer[r] = mant10 * pow(10, exp10);

Return
Nothing

Code Example

The following code example uses the InitFloat10_F32 function.

The SMK900.evi file used for this example can be downloaded at the bottom of this page.
/* Example Code
* InitFloat10_F32
*
* get r, mant10, exp10
* set buffer in memory
* get buffer at r
* if params used 
* 	return result buffer on 32 bits
* else
*	return 0x00 (buffer pas ok) or 0x01 (buffer ok)
*
* example VMExecuteCmd:
* cmd: 															   |r        |mant10   |exp10
*		0xfb 0x0e 0x00 0x0c 0x00 0x0e [0x?? 0x?? 0x?? = macAdress] 0x00 0x00 0xFB 0xFF 0xFF
* rsp: 	0xfb 0x08 0x00 0x2d 0x00 0xe1 0x1e 0x00 0x00 0x00 0xbf
