Module std.math.operations
This is a submodule of std
.
It contains several functions for work with floating point numbers.
Functions
Name | Description |
---|---|
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. |
