## ◆ floatToHalf()

static unsigned short nkMaths::FloatEncoder::floatToHalf | ( | float | v | ) |
| static

Allows to convert a 32bits floating point encoded value into a 16bits (half) floating point representation.
Half floats have 1 bit for sign, 5 bits for the exponent and 10 bits for the fractional part.

Parameters

  v | The float to convert.

Returns
  The half float equivalent, encoded in a short.

Remarks
  Note that this operation can lose information and loss of precision can be observed. Also, subnormal numbers (exponent = 0s) can have a shift in their values, as the IEEE-754 norm interpret them differently between half ans floats.

## ◆ halfToFloat()

static float nkMaths::FloatEncoder::halfToFloat | ( | unsigned short | v | ) |
| static

Allows to convert a 16bits (half) floating point encoded value into a 32bits floating point representation.
Floats have 1 bit for sign, 8 bits for the exponent and 23 bits for the fractional part.

Parameters

  v | The half float to convert.

Returns
  The float equivalent.

Remarks
  Note that for subnormal numbers (exponent = 0s) can have a shift in their values, as the IEEE-754 norm interpret them differently between half ans floats.
