Calculator more accurate than Excel?

Got into a math debate with a colleague today.
Product A cost $0.05 per minute. Find the cost for 15 second.

0.05 / 60 * 15

Using Calculator, she got 0.012499999……
Using Excel, I get 0.0125

So she claims that calculator is more accurate because it gives you more decimal points….

But it doesn’t make sense. How could a caculator be more accurate than Excel? And 0.05 / 60 * 15 is also equal to 0.05 / 4 which gives you 0.0125

So why does the calculator give 0.01249999 instead of 0.0125?
0.05 / 60 will be rounded off when you use calculator. Then you times 15 on something that has been rounded, of cos the result will not be accurate.


Don’t understand why some people likes the physical caculator so much. There are so many thing that need to be caculated at 1 shot. All the raw data are already in excel and the formula is more or less the same. Instead of keying them one by one on the caculator, why not just use excel?

Besides, excel is 100% more accurate than caculator.

Lesson we learnt today:
Being slow and steady doesn’t means you’ll always be correct.
Being fast doesn’t mean you’ll be wrong.

Doing what i excel best

Its been a long time since I was assigned a task that I excel in. Ever since I was transfered to another sub team, I’ve been doing new stuff that I’m not familar with. The feeling of being unsure of many thing that I do isn’t great. Sometimes feel so shitty because I just don’t understand how a lot of things work. Can be quite demoralising sometimes.

When I saw the email saying we need to do that task that I excel in, I was kinda delighted. Its been a long time since I’m assigned with something that I know exactly what I doing and feel that I’m in total control. Its sort of like an ego booster.

The task has been completed. The after-feeling is great.

Now, back to the new stuff that I’m not familar with.

Waive the charges

I always thought this is a known fact until I bump into a few people who never knew about this.

It is possible to get the credit card company to waive the annual fee charges. Almost 99.9% chance of getting it waived. I just called up Citibank yesterday to get them to waived that $60 annual fee on my Ready Credit account which I never use. Its simple, just call and tell them to waive it. No questions asked. If they don’t (Which I heard some customer service does), just say you would like to cancel it. And they will offer to waive it for you. Even if you never used the card before, they will most likely waive it for you too. After all, they rather you hold the card and use it than earn that mere $60 from you.

Anyone paid annual fee for credit cards? I hope not. But I heard that its harder to get waiver for Gold card and Platinum card. Not sure if it is true.

Anyway, its not only annual fee that can be waived. Late payment charges, together with the interest incured, can be waived too. I forgot to pay the bill for my UOB mini few weeks back. So I called to ask for waiver. The customer service ask why I didn’t pay on time and I simply replied that I forgotten. And he waive that $25 late payment charges and interest. OK, this trick only works after you pay your bills.

If they refuse to waive it, just say you want to cancel the card. Simple as that.

2 phone calls to 2 credit card companies and saved me $85. :D

Ganna Spammed Part 2

Ganna Spammed again.

This time, its worst…. 68 junk comments on my blog. Within a span of 3mins…. Obvious its some program. No superhuman can spam at this rate.

I really really don’t want to turn on the word verification. I don’t wanna make it troublesome to post comment. I don’t see why I should take up such measures just because some low-life spammer come spam my blog.

Just like today, I wanted to throw away a plastic bag. I was at the MRT station already. There are no dustbin in MRT station because they scared that terrorist would place a bomb inside. But its troublesome of everyone else. In the end, I have to walk out of the station just to throw that rubbish.

I hate spammer. I hate Osama.
