Type Conversion Functions

It is easy to transform the type of an entity,

• REAL(i) converts i to a real approximation,
• INT(x) truncates x to the integer equivalent,
• DBLE(a) converts a to DOUBLE PRECISION,
• IACHAR(c) returns the position of CHARACTER c in the ASCII collating sequence,
• ACHAR(i) returns the character in the ASCII collating sequence.

All above are intrinsic functions. For example,

    PRINT*, REAL(1), INT(1.7), INT(-0.9999) 
    PRINT*, IACHAR('C'), ACHAR(67)

are equal to

    1.000000 1 0
    67 C
