Please explain SVG Path Commands and Coordinates

In an SVG file, I found a path which looks like this:

<path id="kvg:0548b-s7" kvg:type="㇐b" d="M65.32,48.38c5.65-0.95,12.61-2.46,18.92-3.42c2.05-0.45,4.13-0.5,6.23-0.13"/>

Can somebody explain what the coordinates 48.38c5.65-0.95 and 18.92-3.42c2.05-0.45 represent?

I think that some of the confusion comes from the tricks the format allows for separating individual parameters to the various path operands. So in the example:

M65.32,48.38c5.65-0.95,12.61-2.46,18.92-3.42c2.05-0.45,4.13-0.5,6.23-0.13

You see parameters

• separated by commas as in M(ove)65.32,48.38 ...
• separated by hyphens (minus signs) as in c(ubic bezier)2.05-0.45 ...
• delimited by new operands as in ...48.38c5.65...
• you'll also see parameters delimited by white space instead of commas
• you might even see parameters delimited by a leading period if the preceding parameter had a period in it
• Sometimes you will see parameters in scientific notation as in 3.22e-9 to eliminate zeros

As each kind of operand needs exactly a certain number of parameters (M,L,T need 2; H,V need 1; Q,S need 4; C needs 6; A needs 7; and Z needs 0) you will see situations where operands are omitted. If you see a L with 4 parameters after it, it actually means 2 lines, a C with 18 parameters after it means 3 cubic Beziers.

This is all to minimize any wasted space in the SVG, and not just to make it hard to read.
