## Function Documentation

GLM_FUNC_DECL int glm::findNSB | ( | genIUType | x,
|  | int | significantBitCount
| ) |  |

Returns the bit number of the Nth significant bit set to 1 in the binary representation of value.

If value bitcount is less than the Nth significant bit, -1 will be returned.

Template Parameters

  genIUType | Signed or unsigned integer scalar types.

GLM_FUNC_DECL bool glm::isMultiple | ( | genIUType | v,
|  | genIUType | Multiple
| ) |  |

Return true if the 'Value' is a multiple of 'Multiple'.

GLM_FUNC_DECL bool glm::isPowerOfTwo | ( | genIUType | v | ) |

Return true if the value is a power of two number.

Higher multiple number of Source.

Template Parameters

  genIUType | Integer scalar or vector types.

Parameters

  v | Source value to which is applied the function
  Multiple | Must be a null or positive value

GLM_FUNC_DECL genIUType glm::prevMultiple | ( | genIUType | v,
|  | genIUType | Multiple
| ) |  |

Lower multiple number of Source.

Template Parameters
