 * Truly constexpr functions
-** Compilable with C++20 standard
+** Compilable with C{pp}20 standard
 ** Most of the functions are implemented as templates
 *** Completely inlinable functions
 *** The functions can be evaluated at compile time
 ** No malloc required
-** Works without libstdc++
+** Works without libstdc{pp}
 * IEEE 754 compliant
 ** Supports subnormal numbers, NaN, infinity, and signed zero
