_inlined_description: _

Returns the number of bits set to 1 in the binary representation of value.

**Type parameters:**

T Signed or unsigned integer scalar or vector types.

###vecType< T, P > glm::bitfieldExtract(T, &Value = P, Offset, Bits)

_inlined_description: _

Extracts bits [offset, offset + bits - 1] from value,
returning them in the least significant bits of the result.
For unsigned data types, the most significant bits of the
result will be set to zero. For signed data types, the
most significant bits will be set to the value of bit offset + base - 1.

If bits is zero, the result will be zero. The result will be
undefined if offset or bits is negative, or if the sum of
offset and bits is greater than the number of bits used
to store the operand.

**Type parameters:**

T Signed or unsigned integer scalar or vector types.

###vecType< T, P > glm::bitfieldInsert(T, &Base = P, T, &Insert = P, Offset, Bits)

_inlined_description: _

Returns the insertion the bits least-significant bits of insert into base.

The result will have bits [offset, offset + bits - 1] taken
from bits [0, bits - 1] of insert, and all other bits taken
directly from the corresponding bits of base. If bits is
zero, the result will simply be base. The result will be
undefined if offset or bits is negative, or if the sum of
offset and bits is greater than the number of bits used to
store the operand.

**Type parameters:**

T Signed or unsigned integer scalar or vector types.

Returns the bit number of the least significant bit set to
1 in the binary representation of value.
If value is zero, -1 will be returned.

###vecType< int, P > glm::findMSB(T, &v = P)

_inlined_description: _

Returns the bit number of the most significant bit in the binary representation of value.
For positive integers, the result will be the bit number of the most significant bit set to 1.
For negative integers, the result will be the bit number of the most significant
bit set to 0. For a value of zero or negative one, -1 will be returned.

**Type parameters:**
