ldexp

Description

Construct float from mantissa and exponent.

Signature

T ldexp<T>(
    T x,
    T exp)
    where T : __BuiltinFloatingPointType;

vector<T, N> ldexp<T, N:int>(
    vector<T, N> x,
    vector<T, N> exp)
    where T : __BuiltinFloatingPointType;

matrix<T, N, M> ldexp<T, N:int, M:int>(
    matrix<T, N, M> x,
    matrix<T, N, M> exp)
    where T : __BuiltinFloatingPointType;

T ldexp<T, E>(
    T x,
    E exp)
    where T : __BuiltinFloatingPointType
    where E : __BuiltinIntegerType;

vector<T, N> ldexp<T, E, N:int>(
    vector<T, N> x,
    vector<E, N> exp)
    where T : __BuiltinFloatingPointType
    where E : __BuiltinIntegerType;
