std conv

Parses a character range to a floating point number.

  1. Target parse(Source source)
  2. Target parse(Source s)
  3. Target parse(Source source, uint radix)
  4. Target parse(Source s)
  5. Target parse(Source source)
    Target
    parse
    (
    Target
    Source
    )
    (
    ref Source source
    )
    if (
    isInputRange!Source &&
    isSomeChar!(ElementType!Source)
    &&
    !is(Source == enum)
    &&
    isFloatingPoint!Target
    &&
    !is(Target == enum)
    )
  6. Target parse(Source s)
  7. Target parse(Source s)
  8. Target parse(Source s)
  9. Target parse(Source s, dchar lbracket, dchar rbracket, dchar comma)
  10. Target parse(Source s, dchar lbracket, dchar rbracket, dchar comma)
  11. Target parse(Source s, dchar lbracket, dchar rbracket, dchar keyval, dchar comma)

Parameters

Target

a floating point type

source Source

the lvalue of the range to parse

Return Value

Type: Target

A floating point number of type Target

Throws

A ConvException if source is empty, if no number could be parsed, or if an overflow occurred.

Examples

import std.math : approxEqual;
auto str = "123.456";

assert(parse!double(str).approxEqual(123.456));
