printf scientific notation?

I'll try this again, with a new topic and a better description. Can PHP print floating point numbers using scientific notation? (like 1.32e+5) sscanf reads them ok using %f, but I'd like to print them with %e or %g and the printf documentation doesn't mention them. I've tried %e anyway and it fails to print the exponent part. I've looked at the source code to PHP a little but with the IFDEFs I'm not sure which routine is actually being used. I sort of have the impression it is just calling the C routines directly so the %e and %g should work? Linux (RH 7.1), Apache (1.3.20), PHP (4.0.6) Thanks. -- Bill Rausch, Software Development, Unix, Mac, Windows Numerical Applications, Inc. 509-943-0861 bill@numerical.com
