Name: LMIC_f2sflt16()
Function:
Encode a floating point number into a uint16_t.
Definition:
uint16_t LMIC_f2sflt16(
float f

Description:
The float to be transmitted must be a number in the range (-1.0, 1.0).
It is converted to 16-bit integer formatted as follows:
bits 15: sign
bits 14..11: biased exponent
bits 10..0: mantissa
The float is properly rounded, and saturates.
Note that the encoded value is sign/magnitude format, rather than
two's complement for negative values.
Returns:
0xFFFF for negative values <= 1.0;
0x7FFF for positive values >= 1.0;
Otherwise an appropriate float.

Name: LMIC_f2sflt12()
Function:
Encode a floating point number into a uint16_t using only 12 bits.
Definition:
uint16_t LMIC_f2sflt16(
float f
);
Description:
The float to be transmitted must be a number in the range (-1.0, 1.0).
It is converted to 16-bit integer formatted as follows:
bits 15-12: zero
bit 11: sign
bits 10..7: biased exponent
bits 6..0: mantissa
The float is properly rounded, and saturates.
Note that the encoded value is sign/magnitude format, rather than
two's complement for negative values.
Returns:
0xFFF for negative values <= 1.0;
0x7FF for positive values >= 1.0;
Otherwise an appropriate float.
