std.math

  • Contains the elementary mathematical functions (powers, roots,
  • and trigonometric functions), and low-level floating-point operations.
  • Mathematical special functions are available in std.mathspecial. *
  • The functionality closely follows the IEEE754-2008 standard for
  • floating-point arithmetic, including the use of camelCase names rather
  • than C99-style lower case names. All of these functions behave correctly
  • when presented with an infinity or NaN.
  • The following IEEE 'real' formats are currently supported:
    • 64 bit Big-endian 'double' (eg PowerPC)
    • 128 bit Big-endian 'quadruple' (eg SPARC)
    • 64 bit Little-endian 'double' (eg x86-SSE2)
    • 80 bit Little-endian, with implied bit 'real80' (eg x87, Itanium)
    • 128 bit Little-endian 'quadruple' (not implemented on any known processor!)
    • Non-IEEE 128 bit Big-endian 'doubledouble' (eg PowerPC) has partial support
  • Unlike C, there is no global 'errno' variable. Consequently, almost all of
  • these functions are pure nothrow. *
