| 31 | The <code class="computeroutput"><span class="keyword">typedef</span> <span class="identifier">float_least</span><span class="special">#</span><span class="identifier">_t</span></code>, with | |
| 32 | # replaced by the width, designates a floating-point type with a <span class="bold"><strong>width of at least # bits</strong></span>, such that no floating-point | |
| 33 | type with lesser size has at least the specified width. Thus, <code class="computeroutput"><span class="identifier">float_least32_t</span></code> denotes the smallest floating-point | |
| 34 | type with a width of at least 32 bits. | |
| 35 | </p> | |
| 36 | <p> | |
| 37 | Minimum-width floating-point types are provided for all existing exact-width | |
| 38 | floating-point types on a given platform. | |
| 39 | </p> | |
| 40 | <p> | |
| 41 | For example, if a platform supports <code class="computeroutput"><span class="identifier">float32_t</span></code> | |
| 42 | and <code class="computeroutput"><span class="identifier">float64_t</span></code>, then <code class="computeroutput"><span class="identifier">float_least32_t</span></code> and <code class="computeroutput"><span class="identifier">float_least64_t</span></code> | |
| 43 | will also be supported, etc. | |
