Trigonometric, Exponential, Root, and Logarithmic Intrinsic Procedures

インテル® Fortran コンパイラー 19.0 デベロッパー・ガイドおよびリファレンス

The following table lists intrinsic procedures for trigonometric, exponential, root, and logarithmic operations.

NOTE

Many routines in the LIBM library (Math Library) are more highly optimized for Intel® microprocessors than for non-Intel microprocessors.
