Numbers can either be integers or single-precision floating-point numbers with a
maximum precision of 6 to 7 decimal digits. Except for borehole collar X and Y
coordinates, which can be double-precision floating-point numbers with a maximum
precision of 15 decimal digits.
Numbers can optionally be prefixed with a -/+ to indicate a negative or positive
number.
Decimal numbers can only contain a single dot (.) to indicate the decimal place.
Numbers can be expressed using scientific notation, for example, 1.23E4.
Numbers cannot contain commas or other non-digit characters other than those defined
above. This means that language-specific formatting is not supported.
