Member Function Documentation

float16_IEEE11073_to_IEEE754()

float FloatTypes::float16_IEEE11073_to_IEEE754 ( const uint16_t  raw_bt_float16_le )

static

Converts a 'IEEE-11073 16-bit SFLOAT' to std IEEE754 float.

raw_bt_float16_le is in little-endian, 2 bytes. Exponent at highest byte.

Definition at line 81 of file DataTypes.cpp.

float32_IEEE11073_to_IEEE754()

float FloatTypes::float32_IEEE11073_to_IEEE754 ( const uint32_t  raw_bt_float32_le )

static

Converts a 'IEEE-11073 32-bit FLOAT' to std IEEE754 float.

Example: Temperature measurement, GattCharacteristicType::TEMPERATURE_MEASUREMENT.

raw_bt_float32_le is in little-endian, 4 bytes. Exponent at highest byte.
