std.floatarr

A packed, fixed-size array of float (a double).

Same shape as std.intarr and std.longarr. Packed contiguous doubles are what a numeric routine wants: samples, coordinates, a column of measurements.

import std.floatarr

main() {
    a, err = floatarr.new_filled(2, 1.5)
    println("size=${floatarr.size(a)} err='${err}'")

    value, gerr = floatarr.get(a, 1)
    println("a[1]=${value} err='${gerr}'")

    floatarr.free(a)
}

size=2 err=''
a[1]=1.5 err=''

Float text here follows the C locale, so 1.5 prints with a point on every platform — see std.number for locale-aware rendering.

std.sort sorts one in place with sort.floats.
