Module std.math.operations

This is a submodule of std.math.

It contains several functions for work with floating point numbers.


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