Real

The range specification is of the form

lower:upper

where lower and upper specify the lower and upper allowed range. A missing end of range (or a `*') implies negative or positive infinity. The above is inclusive of the endpoints. A `(' (or `)') before (or after) the lower (or upper) range specifies an open endpoint.

The numbers written in a param.ccl file are interpreted as C code. To express a number in `scientific notation', use, e.g. `1e-10', which is a double precision constant in C. (If the floating precision of the variable to which it is assigned is not double, then C will typecast appropriately. If you really want to specify a single precision floating constant, or a long double constant, append the number with f or < respectively.)
