Functions

NaN real NaN(ulong payload): Create a quiet NaN, storing an integer inside the payload.
approxEqual deprecated bool approxEqual(T value, U reference, V maxRelDiff, V maxAbsDiff): Computes whether a values is approximately equal to a reference value, admitting a maximum relative difference, and a maximum absolute difference.
cmp int cmp(const(T) x, const(T) y): Defines a total order on all floating-point numbers.
fdim real fdim(real x, real y): Returns the positive difference between x and y.
feqrel int feqrel(X x, X y): To what precision is x equal to y?
fma real fma(real x, real y, real z): Returns (x * y) + z, rounding only once according to the current rounding mode.
fmax F fmax(F x, F y): Returns the larger of x and y.
fmin F fmin(F x, F y): Returns the smaller of x and y.
getNaNPayload ulong getNaNPayload(real x): Extract an integral payload from a NaN.
isClose bool isClose(T lhs, U rhs, V maxRelDiff, V maxAbsDiff): Computes whether two values are approximately equal, admitting a maximum relative difference, and a maximum absolute difference.
nextDown real nextDown(real x)
double nextDown(double x)
float nextDown(float x): Calculate the next smallest floating point value before x.
nextUp real nextUp(real x)
double nextUp(double x)
float nextUp(float x): Calculate the next largest floating point value after x.
nextafter T nextafter(T x, T y): Calculates the next representable value after x in the direction of y.
