php - Convert .5 into 1/2 -


i want convert number ends in .5 displays number followed ½, don't want 0.5 display 0½ did this:

$used = str_replace("0.5", "½", $used); $used = str_replace(".5", "½", $used);

however i've realised converts 20.5 2½ instead of 20½.

i'm sure there's better way of doing don't know how.

examples:

5 returns "5" 5.5 returns "5½" 0.5 returns "½" 10.5 returns "10½"

i don't believe duplicate of existing question because code replace or return "1/2" rather "½"

php code demo(in html work fine)

<?php $number="10.5000"; if(preg_match("/^[1-9][0-9]*\.5[0]{0,}$/", $number)) {     echo $used = preg_replace("/\.5[0]{0,}$/", "&frac12;", $number); } elseif(preg_match("/^[0]*\.5[0]{0,}$/", $number)) {     echo $used = str_replace("$number", "&frac12;", $number); } else {     echo $number; }

output: 10½

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod

thorough guide for profiling racket code -

did googling ("racket profiling", "racket measure performance"), didn't find , there no examples in docs. did google "profile" search on htdp - no luck. (profile (f ...)) output isn't obvious other small snippets. ideally want python's python -m cprofile usage examples. when search "python profiling", both duckduckgo , google give top result: 26.4. python profilers . (although scanned quickly, seems more of reference "thorough usage guide" examples. if had else in mind, perhaps please link that?) the equivalent racket documentation be: profile: statistical profiler . a usage example: #lang racket (require profile) (profile-thunk (thunk (function-to-profile arg0 arg1) )) here (thunk e) convenience (lambda () e) . bigger example: #lang racket (module mod racket (provide f) (define (f) (for/list ([i 10000]) i))) (require (prefix-in mod: 'mod)) (define (f) (for ([i 10000
