If you want to make a high precision calculation with Perl you could use the bignum module.As little example:
|
1 2 3 4 |
#!/usr/bin/perl print 4/3,"\n"; use bignum; print 4/3,"\n"; |
And we could see the second result has a better accuracy than the default:
|
1 2 |
1.33333333333333 1.333333333333333333333333333333333333333 |
But you could improve this by setting the precision in Significant figures, like in this example we want 60.
|
1 2 3 4 |
#!/usr/bin/perl print sqrt(20),"\n"; use bignum ( p => -60 );; print sqrt(20),"\n"; |
As result we get:
|
1 2 |
4.47213595499958 4.472135954999579392818347337462552470881236719223051448541794 |
