dart double type doesn't allow fixed format -

-

मैं निम्नलिखित कोड का उत्पादन करता हूं: 

  [v.bankClosingBalance, 0.00]। पहलेवाले ( (मान) = & gt; मान! = नल)   
 और त्रुटि प्राप्त करें:  
  अपवाद: अनचाहे त्रुटि: प्रकार 'डबल' का कोई उपप्रकार नहीं है 'मान' का 'स्ट्रिंग' टाइप करें   
 जो ठीक है क्योंकि यह मुझे इसकी दोहरी बताता है समस्या एक डबल के रूप में है जो मुझे करने में सक्षम होना चाहिए:  
  [v.bankClosingBalance, 0.00]। पहलेवाले ((मान) = & gt; मूल्य! = शून्य) .toStringAsFixed (2)   
 लेकिन यह मुझे त्रुटि देता है:  
  अपवाद: अनचाहे त्रुटि: 'int' प्रकार 'मान' का 'स्ट्रिंग' प्रकार का एक उपप्रकार नहीं है।   
 अगर मैं इसके चारों ओर दोहरी पीढ़ी का उपयोग करता हूं तो यह अभी भी 'डबल' को छोड़कर कहता है।  
 मुझे यहाँ क्या याद आ रही है?   
 
 
 मुझे पूरा यकीन है  v.bankClosingBalance  आपकी अपेक्षाओं को वापस नहीं लौटाता है। 
 मैं इस समस्या को पुन: उत्पन्न नहीं कर पा रहा हूं।

php - How can I cram 6+31 numeric characters into 22 alphanumeric characters? -

-
I have a 6 digit number and a 31-digit number (such as "234536" and "201103231043330478311223582826") that I The API needs to be crawled in the same 22-character alphanumeric field that uses PHP. I tried to convert each one to 32 (using custom code could not handle the base_convert () large number) and to connect with a single-character delimiter, but It only gives me 26 characters This is a restore API, so the letters should be URI-protected. I would like to do a database table cross with two references without reference to another reference value, if possible, any suggestions? Instead use a radix of 62. This will give you 22 characters for the top, 3.35 for the pre and 17.3 for the next. & gt; & Gt; & Gt; Math.log (10 ** 6) /math.log (62) 3.3474826039165504 & gt; & Gt; & Gt; Math.log (10 ** 31) /math.log (62) 17.295326786902177
