Format a number in scientific notation

Use the [scientific] method. This example shows the longhand and scientific notation representations for various common numbers.

Code

var( constants = map( 'c' = decimal(299792458),
                      'G' = decimal(0.0000000000667300)) )

$constants->forEachPair => {^
     #1->first+' = '+#1->second+' = '+scientific(#1->second)+'\n'
^}

Result

c = 299792458.000000 = 2.99792458E8
G = 0.000000 = 6.673E-11
