Real Value Type

A real number denotes all fractional and non-fractional values.

This value is defined as a double precision floating point number, according to the IEEE754 standard.

Real values in Dinamica EGO use the standard representation for floating point numbers.

• 1, 2, 198, etc.
• -1, -2, -198, etc.
• -1.002, -2321.3441, -198.4455, etc.
• 5.45e-32, -34.211e+45, etc. (Syntax MeE, where M is a mantissa and E is the exponent. It denotes M*10^E)

• Converted from: Integer Value Type — lossless; widening, every integer is exactly representable as a real. Non Negative Integer Value Type. Positive Integer Value Type. Boolean Value Type — True → 1, False → 0. Index Or Name Type — can fail; only succeeds if the value holds an index rather than a name. String Type — can fail; the string must parse as a valid number (e.g. “test” fails, “3.14” succeeds). Log Tag Type — converts to the level's number (e.g. Info → 4). Cell Type — converts to the cell type's number (e.g. Signed 32 Bit Integer → 5). Table Value Type — can fail; only succeeds if the value actually holds a Real Value.

• Converted to: Boolean Value Type — zero → False, any non-zero value → True. Enum Type. Index Or Name Type. Integer Value Type — lossy; truncates the fractional part. Non Negative Integer Value Type — can fail on negative input; lossy (truncates) otherwise. Positive Integer Value Type — can fail when not positive; lossy (truncates) otherwise. Null Value Type. Log Tag Type — the number selects the level by its position in Log Tag Type's table (e.g. 4 → Info). Cell Type — the number selects the cell type by its position in Cell Type's table (e.g. 5 → Signed 32 Bit Integer). Percent Type. String Type. Date Type. Table Cell Type. Table Value Type. Tuple Type.
