In M, numeric literals (numlit) are entered without surrounding delimiters.

Example:

       GTM>WRITE 1
       1
       GTM> WRITE 1.1
       1.1
        

These display numeric literals that are integer and decimal.

M also accepts numeric literals in the form of a mantissa and an exponent, separated by a delimiter of "E" in uppercase. The mantissa may be an integer or a decimal fraction. The integer exponent may have an optional leading minus sign (-).

Example:

       GTM>WRITE 8E6
       8000000
       GTM> WRITE 8E-6
       .000008
       GTM>
