The number of radix digits that be represented without change: for integer types, the number of non-sign bits in the mantissa; for floating types, the number of radix digits in the mantissa.

Definition at line 200 of file limits.

The number of base 10 digits that can be represented without change.

Definition at line 202 of file limits.

See std::float_denorm_style for more information.

True if the type has a representation for positive infinity.

Definition at line 235 of file limits.

True if the type has a representation for a quiet (non-signaling) 'Not a Number.'

Definition at line 238 of file limits.

True if the type has a representation for a signaling 'Not a Number.'

Definition at line 241 of file limits.

Definition at line 254 of file limits.

True if the type uses an exact representation. 'All integer types are exact, but not all exact types are integer. For example, rational and fixed-exponent representations are exact but not integer.' [18.2.1.2]/15

Definition at line 215 of file limits.

True if-and-only-if the type adheres to the IEC 559 standard, also known as IEEE 754. (Only makes sense for floating point types.)

Definition at line 250 of file limits.

True if the type is integer.

Definition at line 210 of file limits.

True if the type is modulo, that is, if it is possible to add two positive numbers and have a result that wraps around to a third number that is less. Typically false for floating types, true for unsigned integers, and true for signed integers.

Definition at line 259 of file limits.

True if the type is signed.

Definition at line 204 of file limits.

This will be true for all fundamental types (which have specializations), and false for everything else.

Definition at line 195 of file limits.

The maximum positive integer such that radix raised to the power of (one less than that integer) is a representable finite floating point number.

Definition at line 229 of file limits.

The maximum positive integer such that 10 raised to that power is in the range of representable finite floating point numbers.

Definition at line 232 of file limits.

The minimum negative integer such that radix raised to the power of (one less than that integer) is a normalized floating point number.

Definition at line 222 of file limits.

The minimum negative integer such that 10 raised to that power is in the range of normalized floating point numbers.

Definition at line 225 of file limits.

For integer types, specifies the base of the representation. For floating types, specifies the base of the exponent representation.

Definition at line 218 of file limits.

See std::float_round_style for more information. This is only meaningful for floating types; integer types will all be round_toward_zero.

Definition at line 268 of file limits.

True if tinyness is detected before rounding. (see IEC 559)

Definition at line 264 of file limits.

True if trapping is implemented for this type.
