e

Writing the multiplication symbol (×) and the superscript exponent is tedious, and not suitable for programs. A slightly altered notation is used in computer programs and in input and output text:

 1.38502 × 10+03 =  1.38502e+03
 
 1.38502 × 10-03 =  1.38502e-03
 
-1.38502 × 10+03 = -1.38502e+03

-1.38502 × 10-03 = -1.38502e-03

Caution: For SPIM, only a small "e" is allowed in floating point constants. (Some software systems, such as Java, allow both upper and lower case e's).
